How to work out gcf calculator

In the previous post we have discussed about How to use Least Common Multiple Calculator and In today's session we are going to discuss about How to work out gcf calculator. Greatest Common Factor or Highest Common factor that is abbreviated as GCF, provides the largest numerical value that divides the other numbers with zero remainder .There are some methods of solving the GCF are as division method or factorization method .GCF calculator is an online tool that helps in calculating the factors accurately.  (know more about gcf calculator , here)
There are some examples for defining the GCF calculations are as follows:
Number 24 that is also denoted as 24 = 12 * 2 = 8 * 3 = 4 * 6, that denotes form of product of two integers. If we talk about the divisor of 24 then these are 1 , 2 , 3 , 4 , 6 , 8 , 12 , 24 that divides the 24 and 1 , 2  , 3 , 4 , 6 , 9 , 12 are some divisor of the value 36. There are some common divisor are 1 , 2 , 3 ,6,12 and among these factors greatest common factor is 12 .So the GCF of the 24 and 36 is 12. Finding the gcf with the help of gcf calculator will be very easy process. For finding the gcf with the help of gcf calculator user should enters the list of integers for which they want to find the gcf that is separated by commas or spaces .It will be written as gcf( 36 , 24 ) = 12. For reduce the fraction to its lowest terms we can use gcf and if both numerator and denominator have the common gcf if 14 / 35 = 7 * 2 / 7 * 5 = 2 / 5 as an example of gcf( 14 , 35 ) = 7. In this example gcf calculator define the smaller value as the denominator and higher value as the numerator.

How to use Least Common Multiple Calculator

In the previous post we have discussed about How to use Geometric Mean Calculator and In today's session we are going to discuss about How to use Least Common Multiple Calculator. To understand about the least common multiple calculator, we must first understand the meaning of the multiples. If we write the multiples of a number 5, we say that the numbers 5, 10, 15, 20, 25, 30, 35 . . . . are all the multiples of 5. It simply shows that the numbers which are completely divisible by the given number is it’s multiple.  So we say that the number 10, 15, 20 . . .  are completely divisible by 5, so they are the multiples of 5.  Now to learn about the least common multiples of the given two or more numbers, we say that the common multiples of the factors of the given numbers can be picked and then they are multiplied to get the desired number. Here if we need to find the least common multiple of the given numbers says 25 and 45, we will first write the prime factors of the two numbers and then we will pick the common factors and find their product to get the least common multiple of the given numbers. So we proceed by writing the factors of  25 and 45 as follows :
25 = 5 * 5 * 1
45 = 3 * 3 * 5 * 1
 Here we find the common factors of the two numbers as 5 and 1, so we get the least common multiple of 25 and 45 as 5 * 1 = 5 Ans. (know more about Least common multiple, here)

How to use Geometric Mean Calculator

In the previous post we have discussed about Operations With Integers and In today's session we are going to discuss about How to use Geometric Mean Calculator. In mathematics whenever we study about series then geometric progression is one of the most complicated series. If a, b, c are in geometric progression then b/a = c/a =r here  r is called a common difference and its value will be same for all the elements of geometric progression.
If the value of a =2 , b=4 ,c=8 ,then according to geometric progression b/a = 4/2 , c/a = 8/4
now we get common difference r = 2 . If we have to extend the terms in geometric progression then we have to multiply last term by common difference. As in the above example 8 is last term and if we multiply it by common difference two then we will get 16 that will be the next term of the series.
If we have two numbers a and b and we are asked to calculate the geometric mean then it will be
G= √ab here G is called geometric mean for all the elements. Now we  will see the How we calculate the geometric mean. Suppose we have a two numbers first number a= 2 and another number is b= 8 and these numbers are in G.P then geometric mean will be G=√2*8 = √16 = 4 , in this way we get the geometric mean G= 4. If we talk about geometric mean calculator then it always ask for two values, the values should be in geometric progression, firstly it will multiply two value then it will calculate square root. In this way we can calculate the geometric mean of any two numbers with the help of geometric mean calculator.
Boolean algebra is one of the most important topics in CBSE syllabus so If we want score good marks you should go through Boolean algebra and would read the cbse class 12 sample papers.

Operations With Integers

Integers are endless series of numbers which start from minus infinite and goes up to plus infinite, such that every number in the series has its successor and each number has its predecessor. We will learn that how to perform   Operations with Integers. In order to perform the operations with integers, we say that all the mathematical and the logical operators can be performed on the integers. By logical operations, we mean that we can compare the two integers and arrange the series of integers in ascending or descending order. We know that all the positive integers are greater than 0 and all the negative integers are less than zero. So we come to the conclusion that  if we draw a number line , zero lies in the middle and the more we move towards right the positive number goes on increasing and the more we move towards left, the negative numbers goes on decreasing. So to compare the two numbers we say that the number on the right of the number line is always greater than the number on the left side.  Now we look at the mathematical operations on integers. We can add, subtract, multiply and divide the integers. We say that the integers satisfy the closure property for the addition, subtraction and multiplication operation. But the closure property does not hold true for the division operation. It means that when two integers are added the result is an integer, if two integers are subtracted or multiplied the result is an integer but division of two integers is not an integer every time.
  We can take the guidelines from Free Online Tutoring to understand the topics which we find difficult to solve otherwise. We also have CBSE Sample Papers online to learn about the  concepts of the question papers which have come in the past years for different subjects and In the next session we will discuss about How to use Geometric Mean Calculator.

How to Find The Area of a Circle

In today session we are going to discuss how to find the area of circle. The area of circle can be obtained by the following ways.
1: If we know the radius of the circle.
If the radius r is given then the area of the circle can be calculated by the using the method
   Area of circle = pi*r²
Where r is the radius of the circle and (pi) is the constant having fixed value 3.142 or 22/7
We can also understand how to find the area of circle in the CBSE Books for Class 8.
 2: If we know the diameter d of the circle
If diameter d is given then the area of the circle can be calculated by the using the method
     Area of the circle = pi * d²/4
Where d is the diameter of the circle and (pi) is the constant having fixed value 3.142 or 22/7
This topic is also important to find the confidence interval.
3: if we know the circumference of the circle
If circumference c is given then the area of the circle can be calculated by the using the method
             Area of the circle = c²/4*pi
Where c is the circumference of the circle and (pi) is the constant having value 3.142 or 22/7.
At the end of the above method to determine the area of the circle .there is an another way to find the area of the circle
By using the method of area of sector of the circle = (pi*R²*angle) / 360
Where r is the radius of the circle and (pi) is the constant having fixed value 3.142 or 22/7
For the area of whole circle angle must be equal to 360 degree. Therefore the area of the circle will be = (pi*R²*360) / 360 it implies that
Area of the circle = pi*R²
