What is LCM?
The least common multiple (also called the lowest common multiple, or LCM) of two or more integer numbers is the smallest positive integer divisible by all these numbers.
So, how do you find the LCM of two numbers? It's simpler than you might think. First, list the prime factors of each number. Then, identify the factors that appear in any of the numbers. Finally, multiply each prime factor raised to the highest power it appears in any of the numbers. This will give you the LCM of the two numbers.
For three or more numbers, the process is the same — gather all prime factors and use the highest power of each.
