Multiples

What is a multiple?

The result of multiplying a number by an integer (not a fraction).

In the multiplication table, we can see that

3 6 9 12 15 18 21 24 27 30Therefore, 12 is a multiple of 3,

because 3 × 4 = 12

But 7 is NOT a multiple of 3

Factors and Multiples

• Factors and multiples are associated with multiplication.

• Factors are what you can multiply to get a number.

• Multiples are what you get after multiplying a number by an integer.

3 x 4 = 12factors multiple

List the first 12 multiples of a given 1-digit number

For example, “4”The first 12 multiples are

4 8 12 16 20 24 28 32 36 40 44 48

What is the 8th multiple of the digit ‘4’?

The first 12 multiples are 4 8 12 16 20 24 28 32 36 40 44 48

What is the 8th multiple of the digit ‘4’?

The first 12 multiples are 4 8 12 16 20 24 28 32 36 40 44 48

32 is the 8th multiple of the digit ‘4’.

Find the common multiples of two given 1-digit numbers

Find the common multiple of 3 and 8 which is less than 30.



3 6 9 12 15 18 21 24 27 30

List down the multiples of 3.Step 1:



3 6 9 12 15 18 21 24 27 30

8 16 24 32 40 48 56 64 72 80

List down the multiples of 8.Step 2:



3 6 9 12 15 18 21 24 27 30

8 16 24 32 40 48 56 64 72 80

Circle the common multiple(s).Step 3:



3 6 9 12 15 18 21 24 27 30

8 16 24 32 40 48 56 64 72 80

The common multiple is 24.
