How to find lcm?

A simple way to find the lcm of two or more numbers is to list the first few multiples and then select the lowest.
Find the lcm of 8, 12 and 16
List the first few multiples of 8, 12 and 16
Multiples of 8 are: 8, 16, 24, 32, 40, 48, 56 ...
Multiples of 12 are: 12, 24, 36, 48, 60, ...
Multiples of 16 are: 16, 32, 48, 64,
The lowest (or smallest multiple is 48.

There is also another method to find the lcm based on primes factorization.
