Solution: The LCM of 132 and 107 is 14124 Methods How to find the LCM of 132 and 107 using Prime Factorization One way to find the LCM of 132 and 107 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 132? What are the Factors of 107? Here is the prime factorization of 132: 2 2 × 3 1 × 1 1 1 2^2 × 3^1 × 11^1 2 2 × 3 1 × 1 1 1 And this is the prime factorization of 107: 10 7 1 107^1 10 7 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, 3, 11, 107 2 2 × 3 1 × 1 1 1 × 10 7 1 = 14124 2^2 × 3^1 × 11^1 × 107^1 = 14124 2 2 × 3 1 × 1 1 1 × 10 7 1 = 14124 Through this we see that the LCM of 132 and 107 is 14124. How to Find the LCM of 132 and 107 by Listing Common Multiples The first step to this method of finding the Least Common Multiple of 132 and 107 is to begin to list a few multiples for each number.
