The factors of 6 are 1, 2, 3, and 6. The factors of 18 are 1, 2, 3, 6, 9, and 18.

The only rule I can think of is that the 6 times table is multiples of six. 1 x 6 = 6 2 x 6 = 12 3 x 6 = 18 and so on.

2/6 of 18 = 1/3 of 18 = 18/3 = 6

Numbers are divisible by 6 if they are even and also divisible by 3. Therefore, for example, since 18 is divisible by 3 and 2, it is also divisible by 6.

The factors of 18 are 1, 2, 3 , 6, 9 & 18 because: 1 x 18 = 18 2 x 9 = 18 3 x 6 = 18
