Finding Lowest Common Multiple from Factorizations (Level 2)

This math topic focuses on finding the Lowest Common Multiple (LCM) from given factorizations. It teaches how to identify and choose all distinct factors involved in the factorizations of two numbers to determine their LCM. Each problem presents a pair of numbers expressed through their prime factors, and the task is to select the LCM from a list of options. The problems are incrementally numbered and designed to promote understanding of how to work with prime factorizations to compute LCMs effectively. This is part of a broader unit on factoring and finding LCMs.
