How to find the LCM of 106 and 150 using Prime Factorization

One way to find the LCM of 106 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:

Here is the prime factorization of 106:

2^1 × 53^1

And this is the prime factorization of 150:

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: 2, 53, 3, 5

2^1 × 3^1 × 5^2 × 53^1 = 7950

Through this we see that the LCM of 106 and 150 is 7950.
