##### LCM

LCM stands for “Least Common Multiple.” The least common multiple is defined as the smallest multiple that two or more numbers have in common.

In a magical village, two friends, Alex and Max, loved playing with marbles. They both had their special marble collections. One day, they decided to find out when their collections would have the same arrangement again.

Alex had 4 marbles in his collection, and Max had 6 marbles. They started rolling their marbles, but it seemed to take forever to get the same arrangement.

Suddenly, a friendly wizard named LCM appeared. He told them about the magic of LCM, the Least Common Multiple. LCM was the smallest number that was a multiple of both 4 and 6.
