The answer is 6.You need to do a prime factorization of the 2 numbers first. Then compare the 2 numbers and see what the greatest number they have in common is in the factorization of them. Next times what they have in common and there is your answer. The factorization of 132=11x3x2x2 The factorization of 150=5x5x3x2 There is a 2 and a 3 in each, so you multiply them both and you get 6.
