Example 5: Check whether the first number is a multiple of the
second one.

(a) 675, 25 (b) 124, 12

Solution: (a) To check whether 675 is a multiple of 25, we divide

675 by 25.

2 7
25 6 7 5

– 5 0
1 7 5
– 1 7 5

0 Here, there is no remainder.

So, 675 is a multiple of 25.

(b) To check whether 124 is a multiple of 12, we divide
124 by 12.

1 0
12 1 2 4
– 1 2

0 4
– 0
4 Here, 4 is the remainder.

So, 124 is not a multiple of 12.

Common Multiples

Example 6: Write the multiples of 8 and 12. Also, list out two

common multiples.

Solution: Multiples of 8: 8, 16, 24 , 32, 40, 48 , …

Multiples of 12: 12, 24 , 36, 48 , 60, …

The two common multiples of 8 and 12 are 24 and 48.
