3x^2, 12y, and 10x^3y^3
what is the lcm of these numbers?
More importantly how do you figure out the answer if it is a question with this many powers?
do just like you would with numbers, break them down into prime factors. Then "collect" them so all are represented.
3x^2 = 3*x*x
12y = 3*2*2*y
10x^3y^3 = 2*5*x*x*x*y*y*y
so we need: 2*2*3*5*x*x*x*y*y*y
