HCF and LCM | Numbers | Maths

The video tutorial, led by Lorenzo, explores the concepts of highest common factors (HCF) and lowest common multiples (LCM). It begins with an introduction to factors and multiples, explaining that factors are numbers that divide another number exactly, while multiples are results of multiplying a number by integers. The tutorial then delves into finding the HCF, using examples like 16 and 24, and explains the process of listing factors and identifying the highest common one. It also covers finding the LCM by listing multiples and identifying the smallest common multiple, using examples like 16 and 24, and 15 and 25. The video concludes with practice exercises for viewers to apply their understanding.
