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
