A:
Solution: The LCM of 134 and 17 is 2278 Methods How to find the LCM of 134 and 17 using Prime Factorization One way to find the LCM of 134 and 17 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 134? What are the Factors of 17? Here is the prime factorization of 134: 2 1 × 6 7 1 2^1 × 67^1 2 1 × 6 7 1 And this is the prime factorization of 17: 1 7 1 17^1 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, 67, 17 2 1 × 1 7 1 × 6 7 1 = 2278 2^1 × 17^1 × 67^1 = 2278 2 1 × 1 7 1 × 6 7 1 = 2278 Through this we see that the LCM of 134 and 17 is 2278. How to Find the LCM of 134 and 17 by Listing Common Multiples The first step to this method of finding the Least Common Multiple of 134 and 17 is to begin to list a few multiples for each number.
