HCF and LCM Concepts

This video tutorial explains how to find the Least Common Multiple (LCM) and the Highest Common Factor (HCF) of two or three numbers. It begins with an introduction to the concepts of LCM and HCF, followed by step-by-step examples for calculating the LCM of two and three numbers. The video then transitions to explaining the HCF, also known as the Greatest Common Factor (GCF), with examples for both two and three numbers. The tutorial concludes with a summary of the methods discussed.
