A:
Solution: The LCM of 94 and 83 is 7802 Methods How to find the LCM of 94 and 83 using Prime Factorization One way to find the LCM of 94 and 83 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 94? What are the Factors of 83? 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 83: 8 3 1 83^1 8 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, 83 2 1 × 4 7 1 × 8 3 1 = 7802 2^1 × 47^1 × 83^1 = 7802 2 1 × 4 7 1 × 8 3 1 = 7802 Through this we see that the LCM of 94 and 83 is 7802. How to Find the LCM of 94 and 83 by Listing Common Multiples The first step to this method of finding the Least Common Multiple of 94 and 83 is to begin to list a few multiples for each number.
