Define the following term. greatest common factor

prohojiy [21]

A GCF ( Greatest Common Factor) is one factor that can be split evenly between the two numbers you have chosen.

For example, the greatest common factor of 4 and 8 would be 4 because this is the greatest number that can be split evenly with the numbers I have chosen.
