What numbers have the greatest common factor equal to six?

Answer 1

6 and any multiple greater than 1 of 6, eg 6 and 12, 6 and 18, 6 and 24, etc...

Any two multiples of 6 where the other factors are relatively prime (ie have a gcf of 1), eg 6 and 7 are relatively prime, so 6 x 6 = 36 and 6 x 7 = 42 have a gcf of 6, 2 and 9 are relatively prime, so 2 x 6 and 9 x 6 (12 and 54) have a gcf of 6, etc.

Answer 2

The factors of 6 are 1, 2, 3 and 6. For them to be common, they need to be compared to another set of factors.

Answer 3

No single number has a "common" factor.

"Common" means "same for both". A 'common' factor is a number that's a factor of 2 or more numbers.

Answer 4

6 and 12 have a GCF of 6.

Answer 5

6 and 12, among others.

Answer 6

How about: 12, 18 and 24
