Finding Lowest Common Multiple from Factorizations - 3 Numbers (Level 3)

This math topic focuses on practicing how to find the lowest common multiple (LCM) of three numbers by analyzing their factorizations. Each question presents a set of three numbers in their factorized form, and learners are tasked with identifying the set of all distinct factors that contribute to the LCM. They must then choose the correct LCM from a list of multiple-choice options. The skills exercised here blend understanding factorization and applying this understanding to find the LCM, which are essential components in advanced arithmetic and number theory.
