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
