Answer 27

Answer 28

You were right it is D and A!

Because when @UnkleRhaukaus made you write what was the common factors of 28 it are 1,2,4,7,14, and 28 the common factors of 14 are 1,2,7,and 14 and the common factors of 7 are 1, and 7.

So if you just look at the answer choice right away without even trying to figure out you should know that it is A and D because 3 and 1 don't have a common factor of 7. @TT04

Answer 29

There might also be 1 and 7 actually. @TT04
