Learning focus

Learn about multiples and how to work out the factors of a number.

This lesson includes:

• a catch-up quiz
• a learning summary
• three videos

Multiples of 2

Multiples are really just extended times tables.

The multiples of 2 are all the numbers in the 2 times table, such as:

2, 4, 6, 8, 10 and so on

Multiples of 2 always end with a 2, 4, 6, 8 or 0.

You can tell 2286, for example, is a multiple of 2 because it ends with a 6.

Multiples of 5

The multiples of 5 are all the numbers in the 5 times table, such as:

5, 10, 15, 20, 25 and so on

Multiples of 5 always end with a 5 or a 0.

You can tell 465, for example, is a multiple of 5 because it ends with a 5.

Factors are numbers that divide exactly into another number.

For example, the factors of 8 are:

1, 2, 4, 8

Factors can be shown in pairs. Each pair multiplies to make 8.

The factor pairs of 8 can be shown:

1 x 8 = 8

2 x 4 = 8
