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`
