What is the LCM of 5, 6, 7

Question

I want to know the least common multiple of 5 6 7

Answer 1

since the three numbers in question have no factors in common, the LCM is the product of all three, namely 210.

Answer 2

210. You can find the LCM of consecutive numbers by multiplying them together.

 

If you need to prove it, write out the multiples:

 

5, 10, 15 etc

6, 12, 18 etc

7, 14, 21, etc

 

The first number that appears in all three lines will be 210.
