Finding the HCF and LCM of Numbers and Solving Equations

The video tutorial explains how to find the highest common factor (HCF) and lowest common multiple (LCM) of two expressions, A and B, using a Venn diagram. It then extends the problem to include a third expression, C, and demonstrates how to determine the powers of C by analyzing the HCF and LCM with A and B. The tutorial emphasizes the importance of using the lowest and highest powers for HCF and LCM calculations, respectively.
