Least Common Multiple (LCM)
Definition
The LCM of two numbers is the smallest positive integer that is divisible by both numbers.
Formula
LCM(a, b) = a × b
Example
LCM(12, 18):
计算示例
Find LCM(12, 18).
- 01GCD(12, 18) = 6
- 02LCM = (12 × 18) / 6
- 03= 216 / 6
- 04= 36
常见问题
What is LCM?
The least common multiple is the smallest number that both numbers divide into evenly. For example, LCM(4, 6) = 12.
When is LCM useful?
LCM is used when adding fractions (finding a common denominator), scheduling events that repeat at different intervals, and in number theory.
What is the relationship between GCD and LCM?
GCD(a,b) × LCM(a,b) = a × b. Knowing one lets you calculate the other.
