How to find the least common number in prime factorization?
Step 1. List the first several multiples of each number. Step 2. Look for multiples common to both lists. If there are no common multiples in the lists, write out additional multiples for each number. Step 3. Look for the smallest number that is common to both lists. Step 4. This number is the LCM.
Which is the least common multiple of a number?
Bring down the primes in each column. Multiply the factors to get the LCM. The smallest number that is a multiple of two numbers is called the least common multiple (LCM). The prime factorization of a number is the product of prime numbers that equals the number.
