What is the formula for LCM?

Problem 1. Illustrate the formula lcm(a, b) = a × b / gcd(a, b) by calculating the following examples by using the formula and by calculating the lcm in some other manner and seeing that you get the same value by both methods. It makes perfect sense to talk about the least common multiple of three or more integers.
