What is the LCM of 6 7 8?

Answer 1

b

Answer 2

The Least Common Multiple (LCM) of (6,7,8) is 168.

We can calculate the LCM of three numbers by splitting it up into two LCM calculations. First, we will find the LCM of any two numbers, and then find the LCM of that number, and the last number.

To start, let's find the LCM of 6 and 8. The only common factors of 6 and 8 are 1 and 2, so we will multiply those two numbers to get 2, and divide the 6x8 by 2, getting 24.

Now we need to find LCM(24, 7). The only common factor of 24 and 7 is 1, so the LCM of 6, 7, and 8 is (24x7)/1=168.
