A:
Solution: The LCM of 147 and 50 is 7350 Methods How to find the LCM of 147 and 50 using Prime Factorization One way to find the LCM of 147 and 50 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 147? What are the Factors of 50? Here is the prime factorization of 147: 3 1 × 7 2 3^1 × 7^2 3 1 × 7 2 And this is the prime factorization of 50: 2 1 × 5 2 2^1 × 5^2 2 1 × 5 2 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: 3, 7, 2, 5 2 1 × 3 1 × 5 2 × 7 2 = 7350 2^1 × 3^1 × 5^2 × 7^2 = 7350 2 1 × 3 1 × 5 2 × 7 2 = 7350 Through this we see that the LCM of 147 and 50 is 7350. How to Find the LCM of 147 and 50 by Listing Common Multiples The first step to this method of finding the Least Common Multiple of 147 and 50 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.
