A:
Solution: The LCM of 92 and 44 is 1012 Methods How to find the LCM of 92 and 44 using Prime Factorization One way to find the LCM of 92 and 44 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 92? What are the Factors of 44? Here is the prime factorization of 92: 2 2 × 2 3 1 2^2 × 23^1 2 2 × 2 3 1 And this is the prime factorization of 44: 2 2 × 1 1 1 2^2 × 11^1 2 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, 23, 11 2 2 × 1 1 1 × 2 3 1 = 1012 2^2 × 11^1 × 23^1 = 1012 2 2 × 1 1 1 × 2 3 1 = 1012 Through this we see that the LCM of 92 and 44 is 1012. How to Find the LCM of 92 and 44 by Listing Common Multiples The first step to this method of finding the Least Common Multiple of 92 and 44 is to begin to list a few multiples for each number. If you need a refresher on how to find the multiples of these numbers, you can see the walkthroughs in the links below for each number.
