Answer 7

Without the answer options, how about we factor both numbers? Then someone in possession of the answer options can pick the one which does not appear in our list of factors!

150 = 2*75 = 2*3*25 = 2*3*5*5
450 = 2*225 = 2*3*75 = 2*3*3*25 = 2*3*3*5*5

Any number you can't make up by multiplying the common factors in that list (2, 3, 5, 5) is not a common factor of 150 and 450. For example, you can't make up 9 because there is only 1 3 in common. 15 is a possible factor, because you can multiply 3*5 =15. Etc.
