In math, the expansion of gcf is greatest common factor. A number which is largest number in factors of any two numbers. In other words, the gcf is dividing the other numbers in factors. The prime factors also used for gcf determination.Now we are going to see what a gcf in math. Understanding How to Find Prime Factors is always challenging for me but thanks to all math help websites to help me out.


Explanation for what is gcf in math

Example problems for what is a gcf in math:

Problem 1: What is the greatest common factor for given numbers?

36 and 25

Answer:

Given whole numbers are 30 and 25.

The factors of number 30 are 1, 2, 3, 5, 6, 10, 15, and 30.

The factors of number 25 are 1, 5, and 25.

In this list, we choose the common factor as 1, 5.

Therefore, the greatest common factor of given numbers are 5.

Problem 2: What is the greatest common factor for given numbers?

45 and 81

Answer:

Given numbers are 45 and 81.

The factors of number 45 are 1, 3, 5, 9, 15 and 45.

The factors of number 81 are 1, 3, 9, 27 and 81.

In this list, we choose the common factor as 1, 3 and 9.

Therefore, the greatest common factor of given numbers are 9.
