GCDLCM - Greatest Common Denomerator, Least Common Multiple

Introduction: The greatest common factor of two (or more) numbers is the product of all the prime factors the numbers have in common. The least common multiple (LCM) of two numbers is the smallest number (excluding zero) that is a multiple of both of the numbers..
