The greatest common factor of two numbers is a. the smallest number that is a divisor of both numbers b. the largest number that is a divisor of both numbers c. any common factor of the two numbers d. the largest factor that divides evenly into one number, but not the other

B is the correct answer since the greatest common factor is the greatest common divisor

The correct answer choice is B. "The largest number that is a divisor of both numbers."

A can't be correct, because if we are looking for the greatest common factor, we don't want the smallest number.
C can't be correct, because if we are looking for the greatest common factor, it can't be just any number.
And D can't be correct either. If we are looking to find the greatest common factor of two number, the factor has to divide into both evenly, not just one.

I hope this helps.

Ibelieve the answer would be 7, 13, 23
