GCF and LCM Word Problems Challenge

The video tutorial explains the difference between greatest common factor (GCF) and least common multiple (LCM) through word problems. It provides examples of each type of problem, discusses key concepts and keywords, and demonstrates how to solve an LCM problem using a practical example. The tutorial emphasizes understanding the context of problems to determine whether to use GCF or LCM.
