Exploring Lowest Common Multiples and Highest Common Factors

This video tutorial covers the concepts of common multiples and highest common factors. It begins with a recap of factors and multiples, explaining that multiples are products of a number and another number, while factors are numbers that multiply to form another number. The tutorial provides examples to find the lowest common multiple (LCM) and highest common factor (HCF) for pairs of numbers: 8 and 12, 10 and 15, and 12 and 18. Each example includes a list of multiples and factors, identifying common ones to determine the LCM and HCF. The video concludes with an interactive exercise for viewers to find the LCM and HCF of 6 and 10.
