A:
Solution: The LCM of 119 and 150 is 17850 Methods How to find the LCM of 119 and 150 using Prime Factorization One way to find the LCM of 119 and 150 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 119? What are the Factors of 150? Here is the prime factorization of 119: 7 1 × 1 7 1 7^1 × 17^1 7 1 × 1 7 1 And this is the prime factorization of 150: 2 1 × 3 1 × 5 2 2^1 × 3^1 × 5^2 2 1 × 3 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: 7, 17, 2, 3, 5 2 1 × 3 1 × 5 2 × 7 1 × 1 7 1 = 17850 2^1 × 3^1 × 5^2 × 7^1 × 17^1 = 17850 2 1 × 3 1 × 5 2 × 7 1 × 1 7 1 = 17850 Through this we see that the LCM of 119 and 150 is 17850. How to Find the LCM of 119 and 150 by Listing Common Multiples The first step to this method of finding the Least Common Multiple of 119 and 150 is to begin to list a few multiples for each number.
