Question

If 6 is a common factor of two numbers, which could be the pair?

Options

• 12 and 18

• 8 and 10

• 5 and 15

• 7 and 14

Answer 1

12 and 18

Explanation:

For 6 to be a common factor, both numbers must be divisible by 6.

• 12 ÷ 6 = 2

• 18 ÷ 6 = 3

So, 12 and 18 are the only pair in the options that are both divisible by 6.
