## Multiples

Find out what multiples are with this video from KS2 Maths.

### 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.

Join in with this video from BBC Supermovers to learn about the multiples of 3, 6, 7, 8 and 12.

## Factors

Watch this video from BBC Bitesize as ants arrange themselves into different groups to explain how factors work.

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
