What is the greatest common divisor of `A` and `B`?

Another way to say this is:

`\gcd(`

`A`, `B`) = {?}

`GCD`

The greatest common divisor is the largest number that is a factor (or divisor) of both `A` and `B`.

The only factor (divisor) of 1 is 1.

The factors (divisors) of `A` are `A_FACTORS`.

The only factor (divisor) of 1 is 1.

The factors (divisors) of `B` are `B_FACTORS`.

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

`\gcd(`

`A`, `B`) = `GCD`
