A:
Solution: The LCM of 35 and 127 is 4445 Methods How to find the LCM of 35 and 127 using Prime Factorization One way to find the LCM of 35 and 127 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 35? What are the Factors of 127? Here is the prime factorization of 35: 5 1 Γ— 7 1 5^1 Γ— 7^1 5 1 Γ— 7 1 And this is the prime factorization of 127: 12 7 1 127^1 12 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: 5, 7, 127 5 1 Γ— 7 1 Γ— 12 7 1 = 4445 5^1 Γ— 7^1 Γ— 127^1 = 4445 5 1 Γ— 7 1 Γ— 12 7 1 = 4445 Through this we see that the LCM of 35 and 127 is 4445. How to Find the LCM of 35 and 127 by Listing Common Multiples The first step to this method of finding the Least Common Multiple of 35 and 127 is to begin to list a few multiples for each number.
