## How to recognise multiples

Multiples of 2: Any even integer is a multiple of 2. So if the units/ones digit is 0, 2,4,6 or 8 it is a multiple of 2.

Multiples of 3: If you add the digits of an integer together (and if the answer is more than a single digit add those digits together) and the total is 3, 6 or 9, the number is a multiple of 3.

Multiples of 4: If you halve the number (or divide by 2) and get an even answer, the number is a multiple of 4.

Multiples of 5: All multiples of 5 have either 0 or 5 as the units/ones digit

Multiples of 6: If the number is even and a multiple of 3, it is a multiple of 6.

Multiples of 10: All multiples of 10 have 0 units/ones.

All multiples of 4 are also multiples of 2

All multiple of 6 are also multiples of 3

All multiples of 8 are also multiples of 2 and 4

All multiples of 9 are also multiples of 3

All even multiples of 9 are also multiples of 6

All multiples of 10 are also multiples of 2 and 5
