How do I find the LCM of these items?

Question

Find the LCM of each set of numbers or expressions.

#1. x^2 z^3,x^3 y,y^2 z

#2. 6ab^2,9a^3 b

Answer 1

You need to have 3 x's, 2 y's and 3 z's:

x^3,y^2,z^3 is the LCM

You need to have the LCM of 9 and 6, which is 18 (both 9 and 6 go evenly into 18) and you need 3 a's and 2 b's:

18a^3b^2
