Solution: The LCM of 124 and 99 is 12276 Methods How to find the LCM of 124 and 99 using Prime Factorization One way to find the LCM of 124 and 99 is to start by comparing the prime factorization of each number. To find the prime factorization, you can follow the instructions for each number here: What are the Factors of 124? What are the Factors of 99? Here is the prime factorization of 124: 2 2 × 3 1 1 2^2 × 31^1 2 2 × 3 1 1 And this is the prime factorization of 99: 3 2 × 1 1 1 3^2 × 11^1 3 2 × 1 1 1 When you compare the prime factorization of these two numbers, you want to look for the highest power that each prime factor is raised to. In this case, there are these prime factors to consider: 2, 31, 3, 11 2 2 × 3 2 × 1 1 1 × 3 1 1 = 12276 2^2 × 3^2 × 11^1 × 31^1 = 12276 2 2 × 3 2 × 1 1 1 × 3 1 1 = 12276 Through this we see that the LCM of 124 and 99 is 12276.
