Find the least common multiple.

Write your answer as a constant times a product of single variables raised to exponents.

You can use prime factorization to find the least common multiple (LCM) of the monomials

and

First, write the prime factorization of each monomial.

There are three distinct prime factors: 3, 23, and

This means the LCM has these three prime factors.

Now figure out how many times 3, 23, and

each appears in the prime factorization of the LCM. To do this, find the greatest number of times 3, 23, and

each appears in the prime factorizations of the monomials.

The prime factorization of the LCM has one 3, one 23, and nine

's.

The least common multiple is
