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

📘 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.
