1. Look at the two monomials below.
What is the least common multiple (LCM) of the monomials shown above?
First, i'm assuming there are no exponents. Then i'm going to multiply
the coefficients together forming a single coefficient for each monomial.
9u3v2w4 = 216uvw,
15u4v4w3 = 720uvw,
The LCM is => The largest coefficient(720). If we divided 720 by 216, we would get a remainder. Therefore, 720 is NOT the LCM. So the LCM is > 720.
We try dividing 2160(3*720) by 216 and
we get 10 and NO remainder.
Therefore, the LCM = 2160.
