Identify Multiples of Numbers

This activity is about multiples of numbers.

4, 6, 8, 10 are multiples of 2 because they appear as answers in the 2 times table.

3, 6, 9, 30, 33, 300 are multiples of 3 because they appear as answers in the 3 times table.

 

Multiples go on for ever.

 

It helps to look for patterns - for example, can you find one in these numbers?

5, 10, 15, 20, 25, 30, 35, 40

 

All multiples of 5 end in a 0 or 5.

 

All multiples of 2 end in a 0, 2, 4, 6 or 8.  They are even numbers.

 

Example

Which of these numbers are multiples of 4 which lie between 40 and 50 inclusive?

 

32, 36, 40, 42, 44, 48, 52

 

Answer

Between 40 and 50 inclusive means that we can include 40 and 50.

10 × 4 = 40, so we can start at 40 and add on 4 each time.

 

We get:

40, 44, and 48

 

Clearly, knowing your times tables can really help you with questions to do with multiples!!
