The least common multiple (LCM) of two or more numbers is the smallest positive integer that is divisible by all of those numbers.

Explanation:

• For example, if you want to find the LCM of 4 and 6, you look for the smallest number that both 4 and 6 can divide without leaving a remainder.
• Multiples of 4 are: 4, 8, 12, 16, 20, 24, ...
• Multiples of 6 are: 6, 12, 18, 24, 30, ...
• The smallest common multiple is 12.

Why is LCM useful?

• It is often used when adding, subtracting, or comparing fractions with different denominators.
• It helps in solving problems involving synchronization of repeating events.
