Factors and Multiples Concepts

This video tutorial for grade three students covers the concepts of factors and multiples. It explains that factors are numbers multiplied together to get a product, while multiples are the products of a number's times table. The video provides examples of factors for numbers like 18, 12, and 24, and explains how multiples are derived from times tables, such as multiples of 4 and 6. Additionally, the video briefly introduces the concept of the least common multiple (LCM), explaining it as the smallest multiple shared by two numbers.
