Least Common Multiple (LCM) Calculator
LCM: 0
Formula:
LCM(a, b) = (a × b) / GCD(a, b)
Example:
Numbers: 12 and 18
GCD = 6
LCM = (12 × 18) / 6 = 216 / 6 = 36
LCM(a, b) = (a × b) / GCD(a, b)
Example:
Numbers: 12 and 18
GCD = 6
LCM = (12 × 18) / 6 = 216 / 6 = 36
📘 What is LCM?
The Least Common Multiple (LCM) of two or more integers is the smallest number that is a multiple of all the given numbers.
✅ Example
Find LCM of 12 and 15
- Prime factors:
- 12 = 2² × 3
- 15 = 3 × 5
- LCM = 2² × 3 × 5 = 60
❓ FAQs – People Also Ask
🔹 What is the lowest common divisor?
It’s a misused term. Likely meant to be LCM or GCD. The smallest number that two values divide into is the LCM.
🔹 What is the difference between LCM and GCD?
- LCM: Smallest number both can divide into
- GCD: Largest number that divides both
🔹 Can two numbers have more than one common multiple?
Yes, they have infinitely many. But the LCM is the smallest of them.
🔹 Can LCM be smaller than both numbers?
No. The LCM is always equal to or greater than the largest input number.
