The greatest common factor (gcf) for two or more than two numbers is the largest positive number that divides the numbers without a reminder.

In mathematics, Gcf is used to simplify the common fractions and carrying out basic operations. The greatest common divisor (gcd), is also known as the highest common factor (hcf), greatest common denominator, or greatest common factor (gcf) of two or more non-zero integers.

The GCF Calculator will take any two numbers, and calculate the GCF of those two numbers.
Step 1 : Enter any 2 number in calculator.

Step 2 : List the factors of the First Number and Second Number.

Step 3 : Take out the common factors from both the numbers.

Step 4 : The biggest number which is common in both is the GCF.
