6 a^2b= 3 x 2 x a x a x 2 x b
9ab^2 = 3 x 3 x a x b x b
15 a^2b^2 = 3 x 5 x a x a x b x b

GCF is all the likes times all the non likes
So all of these have 3 x a x b = 3 ab that would be the LCM
GCF = 3 x a x b x 2 x a x 2 x 3 x b x 5 = 180 a^2b^2

6a^2b, 9ab^2, 15a^2b^2

6 : 2 * 3
9 : 3 * 3
15 : 3 * 5

2 * 3 * 3 * 5 = 90

ANS : 90a^2b^2
