How do we use factors?

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

Multiples of 2

An illustration of a young boy holding a caculator and the multiples of 2 - 2,4,6,8,0

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:

2, 4, 6, 8 or 0

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