This video tutorial explains the concepts of Greatest Common Factor (GCF) and Least Common Multiple (LCM) and their applications in solving real-life problems. It provides examples and practice problems to illustrate how to determine whether to use GCF or LCM in different scenarios. Key indicators such as division, grouping, and repetition are discussed to help identify the appropriate method. The video also includes visual aids and step-by-step solutions to enhance understanding.
