Fun Fact
The Least Common Multiple plays a key role in synchronizing repeating events-such as determining when multiple traffic lights or repeating cycles align at the same moment.
Historical Context
The concept of the Least Common Multiple dates back to ancient civilizations studying ratios, fractions, and calendars. It became formally embedded in number theory alongside the Greatest Common Divisor, with the Euclidean algorithm-described over 2,000 years ago-still forming the foundation of modern LCM computation today.
