HCF and LCM

In this lesson, we will learn about the terms 'Lowest Common Multiple' and 'Highest Common Factor'. We will learn how to determine lowest common multiples for small integers by listing and comparing their factors and multiples.

In this lesson, we will find the 'Lowest Common Multiple' of two integers using a Venn diagram to compare their prime factors.

In this lesson, we will find the 'Highest Common Factor' of two integers by comparing their prime factors using a Venn diagram.

In this lesson, we will answer problem solving questions involving determining the lowest common multiple and highest common factor of two integers. We will model solutions to a range of problems including worded questions.
