As a reminder, a 'multiple' is a number that can be divided exactly by another given number, e.g. 8 is a multiple of 2 because 2 divides 8 exactly four times. By the way, 5.4 is a multiple of 1.8 because 1.8 divides 5.4 exactly three times.

In this quiz we shall only be dealing with whole numbers BUT it's a good idea to keep a lookout for multiples when you work with decimals. The times tables that you have learned will help you in this quiz.

A good strategy is as follows: find a likely multiple and check to see if one of the given numbers DOESN'T divide it. If you can't find one, then that's your multiple. If you do find one, then that's NOT your multiple, e.g. 12 doesn't divide 66
6.
Which of the four choices is a multiple of ALL the numbers given?
3, 9, 11
33
27
99
66
33 isn't divisible by 9, 27 isn't divisible by 11 and 66 isn't divisible by 9
7.
Which of the four choices is a multiple of ALL the numbers given?
8, 9, 12
96
72
84
74
96 isn't divisible by 9, 84 is only divisible by 12 and 74 isn't divisible by any of them
8.
Which of the four choices is a multiple of ALL the numbers given?
6, 7, 8
252
42
48
336
A good strategy is as follows: find a likely multiple and check to see if one of the given numbers DOESN'T divide it. If you can't find one, then that's your multiple. If you do find one, then that's NOT your multiple, e.g. 8 doesn't divide 42. TIP! If you see really big likely multiples, try multiplying the given numbers to see if they can form them: 6 × 7 × 8 = 336
9.
Which of the four choices is a multiple of ALL the numbers given?
6, 9, 18
52
