Understanding LCM (KPK) Concepts

This video tutorial explains the concept of the Least Common Multiple (KPK) and demonstrates how to find it using examples. It covers the basic definition of KPK, provides step-by-step methods to find KPK for numbers like 4 and 6, and 3 and 6, and introduces the prime factorization method for determining KPK. Additionally, the video applies the concept of KPK to solve a real-life problem involving shopping schedules, illustrating its practical use.
