These problems help students learn how to find the lowest common multiple (LCM) using factor diagrams (Venn diagrams). Each problem provides two numbers or sets for which students must complete the given factor diagram to accurately determine the LCM. This topic focuses on applying an understanding of factors through visual organizational aids and integrates basic factorization skills with methods for finding LCM efficiently.
