What is the GCF Calculator?

GCF calculator is an online tool that is used to evaluate the largest positive integer from a set of positive integers that can be divided by that number. It helps you to find two or more than two integers' greatest common factor from a given number.

GCF Calculator with Steps

Several methods(factorization method or prime factor) are used to finding the GCF, so it is very difficult for students to choose which method gives them the best result.

To reduce this problem we introduce our greatest common factor calculator that provides you with correct answers to your particular problems.

What is the Greatest Common Factor?

The greatest common factor is the factors that divide the integers and give zero in the remainder. That is why it is known as the Greatest common divisor. It is the most important method in mathematics that reduces fractions into the simplest form and finds the common divisor from them.

The greatest common factor can also be referred to as the greatest common denominator when working with fractions.

The greatest common factor method was discovered by the Greek mathematician Euclid to solve the complex calculation of two or more two integer problems to find the highest or greatest common factors.

How to Calculate GCF Using Greatest Common Factor Calculator?

The greatest common factor can be calculated with different methods like factorization, prime factor to solve integer number problems. To find the highest common factor quickly or easily, use the highest common factor calculator and along with these methods.

Factorization Method

In the factorization method, gcf factor calculator find all the factors of the given numbers. After that, it makes a list of these factors as per the given number.

Then it match all the common factors from the numbers factors. After finding the common factors take the highest common factor for a solution so that factor is our greatest common factor.

Prime Factors / Factorization Method

The prime factor or tree factor method is also used to solve gcf problems in which the given number is written at the top of the tree. It writes all the multiply factors of a given number first and makes a list of all these factors of both numbers.

In this step, highest common factor calculator uses the factorization method in which matches all the common factors and finds the highest number value. That highest value factor is the greatest common factor of the given number.

Division Method

To find the gcf division method is used in which the largest number is divided by the smallest integer. Then gcf finder takes the divisor from the previous step and divides with that divisor.

Gcf factoring calculator repeats this process to use a divisor as a dividend until the remainder does not become zero. After the remainder becomes zero the last divisor you find is the greatest common factor.

Let's see an example of a greatest common factor question with a solution to know how to do manual calculations and to understand the gcf calculator working method.

Example:

What is the Greatest Common Factor of 12 and 8

Solution:

Use the prime factor method to find factors of given numbers

$$ The\; prime\;factors\; of\; 12 \; are: 2, 2, 3 $$

$$ The\; prime\; factors\; of\; 8\; are: 2, 2, 2 $$

$$ Coprime\; numbers\; are\; 2,2 $$

$$ Greatest\; common\; factor \;=\; 2 \times 2 $$

$$ GCF \;=\; 4 $$

Example:

What is the Greatest Common Factor of 24 and 36

Solution

Using the factorization method to get the solution of the greatest common factor,

$$ The\; factors\; of\; 8 \;are: 1, 2, 4, 8 $$

$$ The\; factors\; of\; 12\; are: 1, 2,3, 4, 6, 12 $$

$$ Then\; the\; greatest\; common\; factor\; is\; 4 $$

Example:

What are the Greatest Common Factors of 16 and 24

Solution:

Use the division method to solve the greatest common factor

\require{enclose} \begin{array}{r} 1 \\[-3pt] 16 \enclose{longdiv}{24} \\[-3pt] \underline{-16}\phantom{2} \\ 2 \\[-3pt] 8 \enclose{longdiv}{16} \\[-3pt] \underline{-16}\phantom{2} \\[-3pt] 0 \end{array}
