Example of Finding the Least Common Multiple Using the Prime Factors Method
To find the least common multiple (LCM) of and using the prime factors method:
- Write each as a product of primes: and .
- List the primes and match them vertically: the first and the first are common to both.
- Bring down the numbers from each column: , , , and .
- Multiply the factors: . Therefore, the least common multiple of and is .

An operations manager is using the Prime Factors Method to find the smallest common multiple (LCM) of two different delivery schedules. After writing each schedule's length as a product of prime numbers and matching identical primes vertically in columns, what is the correct rule for selecting the factors to be multiplied?
A facility manager is using the Prime Factors Method to find the Least Common Multiple (LCM) for two equipment maintenance cycles of 12 hours and 15 hours. True or False: According to this method, if a column in the vertical alignment of prime factors contains a prime factor that appears in the factorization of only one of these cycles, that prime factor should be omitted and not brought down for the final multiplication.

An inventory manager needs to coordinate the delivery of two components. Component A arrives every 12 days, and Component B arrives every 18 days. To determine the next day both will arrive simultaneously, the manager uses the prime factors method to find the least common multiple (LCM). Arrange the following steps in the correct order as they would be used to find the LCM of 12 and 18.
