LCM of 18xy^2, 15y^3

90xy³

Step-by-step explanation:

The least common multiple is the smallest multiple that a set of terms has in common.

To find the least common multiple, we factor the two monomials, then take the maximum power of each separate factor.

18xy² = 2 * 3² * x * y²

15y³ = 3 * 5 * y³

LCM = 2 * 3² * 5 * x * y³ = 90xy³

The least common multiple of the two expressions is 90xy³.
