Solution: The LCM of 113 and 110 is 12430 Methods How to find the LCM of 113 and 110 using Prime Factorization One way to find the LCM of 113 and 110 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 113? What are the Factors of 110? Here is the prime factorization of 113: 11 3 1 113^1 11 3 1 And this is the prime factorization of 110: 2 1 × 5 1 × 1 1 1 2^1 × 5^1 × 11^1 2 1 × 5 1 × 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: 113, 2, 5, 11 2 1 × 5 1 × 1 1 1 × 11 3 1 = 12430 2^1 × 5^1 × 11^1 × 113^1 = 12430 2 1 × 5 1 × 1 1 1 × 11 3 1 = 12430 Through this we see that the LCM of 113 and 110 is 12430. How to Find the LCM of 113 and 110 by Listing Common Multiples The first step to this method of finding the Least Common Multiple of 113 and 110 is to begin to list a few multiples for each number.
