It is not possible to give a sensible answer to this question. The least common multiple (LCM) refers to a multiple that is COMMON to two or more numbers (or expressions). You have only one expression in the question: 15xy.
Also, if 5x3y is different from 15xy then multiplication is not commutative in whatever set these belong to. In that case it is impossible to find the LCM without information about the rules of "multiplication" in this set.

What is the least common multiple of the monomial a 3s and s2?
Well, honey, the least common multiple of a monomial like a^3s and s^2 is simply a^3s^2. You just gotta take the highest power of each variable that appears in either monomial, slap 'em together, and there you have it. Math made sassy.
