GCF is the greatest number that is a factor of two (or more) other numbers.

When we find all the factors of two or more numbers, and some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor.

Let us help you find the GCF for your numbers. Just enter the numbers in boxes below.
