Using the prime factors method, what is the least common multiple of 24 and 36?

1. Write 24 as the product of primes: 2 times 2 times 2 times 3. 2. Write 36 as the product of primes: 2 times 2 times 3 times 3. 3. Match the primes vertically: two columns of 2s, one extra 2 from 24, and two 3s. 4. Bring down every column and multiply the factors to get 72. _Source: OpenStax Elementary Algebra (CC BY 4.0), Ch 1 "Foundations", section 1.1 Introduction to Whole Numbers_
