To find the prime factorization, you can follow the instructions for each number here: What are the Factors of 94? What are the Factors of 92? Here is the prime factorization of 94: 2 1 × 4 7 1 2^1 × 47^1 2 1 × 4 7 1 And this is the prime factorization of 92: 2 2 × 2 3 1 2^2 × 23^1 2 2 × 2 3 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, 47, 23 2 2 × 2 3 1 × 4 7 1 = 4324 2^2 × 23^1 × 47^1 = 4324 2 2 × 2 3 1 × 4 7 1 = 4324 Through this we see that the LCM of 94 and 92 is 4324. How to Find the LCM of 94 and 92 by Listing Common Multiples The first step to this method of finding the Least Common Multiple of 94 and 92 is to begin to list a few multiples for each number.
