Prime factor decomposition

In this lesson, we will introduce indices as a way of representing "lots of lots of".

Indices

In this lesson, we will "build" numbers by considering their products and factors. We will also rewrite numbers as a product of factors in different ways.

Prime Building Blocks

In this lesson, we will investigate how to write a number as a product of its prime factors. We investigate the concept of prime factorisation

Prime Factorisation

In this lesson, we will use our knowledge of prime factorisation to deduce the factors of numbers.

Prime Deductions

In this lesson, we will revisit factors and learn about highest common factors.

Highest common factor

In this lesson, we will use venn diagrams to sort prime factors and to help in identifying highest common factors.

Highest common factors and prime factors

In this lesson, we will learn to calculate the lowest common multiple through listing the multiples of a number.

Lowest common multiple

In this lesson, we will use prime factorisation to identify common multiples and the lowest common multiple. We will also use Venn diagrams to sort prime factors.
