    @NickR You should explain your choice instead of just giving out the answer.

    225 doesnt go into 10 50 doesnt go into 3 225 doesnt go into 2 so evens are out if 3 is out so is 6 and 9

    Better :) But doesn't look right though 50 = 2 x 5 x 5 120 = 2 x 2 x 2 x 3 x 5 225 = 15 x 15 = 3 x 3 x 5 x 5 LCM = Least common multiple, isn't it?

    That definitely won't be 5 then... Least common multiple would be 2 x 2 x 2 x 3 x 3 x 5 x 5

    Same as what I've typed. The main problem of the question is to identify what LCM is (definition), and not to confused with HCF (or GCF, you may call).
