GCD and LCM
Welcome! In this lesson, we will learn about GCD and LCM.
Summary
GCD and LCM
Idea:
GCD (Greatest Common Divisor) is the largest number that divides two or more numbers.
LCM (Least Common Multiple) is the smallest number that both numbers divide into.
GCD Example:
GCD of 18 and 24
Largest common factor = 6 → GCD(18, 24) = 6
LCM Example:
LCM of 4 and 5
Smallest common multiple = 20 → LCM(4, 5) = 20
