A:
Solution: The LCM of 52 and 34 is 884 Methods How to find the LCM of 52 and 34 using Prime Factorization One way to find the LCM of 52 and 34 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 52? What are the Factors of 34? Here is the prime factorization of 52: 2 2 × 1 3 1 2^2 × 13^1 2 2 × 1 3 1 And this is the prime factorization of 34: 2 1 × 1 7 1 2^1 × 17^1 2 1 × 1 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, 13, 17 2 2 × 1 3 1 × 1 7 1 = 884 2^2 × 13^1 × 17^1 = 884 2 2 × 1 3 1 × 1 7 1 = 884 Through this we see that the LCM of 52 and 34 is 884. How to Find the LCM of 52 and 34 by Listing Common Multiples The first step to this method of finding the Least Common Multiple of 52 and 34 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.
