Identify Multiples

We will be looking at the multiples of numbers in this activity.

 

Here are the first five multiples of six: 6, 12, 18, 24, and 30

Here are the first five multiples of nine: 9, 18, 27, 36 and 45

 

The list of multiples of a number don't stop just because we reach our twelve times table!! They go on forever!

 

 

There are sometimes easy ways to spot if a number is a multiple of another number.

 

For example:

Any multiple of 10 will end in a zero.

Multiples of 5 end in a zero or a 5.

Multiples of 2 end in an even number: 0, 2, 4, 6 or 8

 

In the list of numbers below, which ones are multiples of 2, 5 or 10?

 

679, 445, 964, 230, 870

 

 

Multiples of 2: these must end in an even number, so that is 964, 230 and 870.

Multiples of 5: these end in a zero or a 5, so that is 445, 230 and 870.

Multiples of 10: these end in a zero, so 230 and 870

 

Was that simple?

 

 

In the following questions, there will also be some harder ones to solve where we will have to do a division calculation. If there is a remainder in our calculation then the number we've divided can't be a multiple of our given number.

 

Let's give it a go!
