What is the greatest common factor of A and B?

Another way to say this is:

\operatorname{GCF_TEXT}(A, B) = {?}

GCD

The greatest common factor is the largest number that is a factor of both A and B.

The only factor of 1 is 1.

The factors of A are A_FACTORS.

The only factor of 1 is 1.

The factors of B are B_FACTORS.

Thus, the greatest common factor of A and B is GCD.

\operatorname{GCF_TEXT}(A, B) = GCD
