Here's a trick for finding them. You pick s and t from the positive integers, but s must be smaller than t . Recognize, model, identify, find, and describe common multiples and least common multiple using numbers 1 to 100. This page runs a script that will return the prime factorization of a positive integer. Of course the bigger the number, the longer it will take.
