Least Common Multiple (LCM) Calculator
Why does finding the smallest number divisible by multiple numbers feel like solving a mystery? Whether you're planning schedules, working on math homework, or just curious about numbers, the Least Common Multiple (LCM) Calculator is here to make your life simpler. Just plug in your numbers, hit calculate, and voilà—you get the LCM instantly. No more manual calculations or second-guessing. This tool is your math sidekick, ready to save you time and effort. Say goodbye to confusion and hello to quick, accurate results!
Enter two or more numbers to find their LCM.
How It Works
The LCM Calculator uses a straightforward method to find the smallest number that all your input numbers divide into evenly. Here’s how it works in simple terms:
- It starts by finding the greatest common divisor (GCD) of two numbers.
- Then, it multiplies the two numbers together and divides by their GCD to get the LCM.
- For more than two numbers, it repeats this process step-by-step until all numbers are included.
For example, if you enter 4 and 6, the tool calculates the LCM (which is 12) because 12 is the smallest number both 4 and 6 divide into without leaving a remainder.
Example Calculations
| Numbers | LCM |
|---|---|
| 2, 3 | 6 |
| 4, 6 | 12 |
| 5, 10 | 10 |
| 8, 12 | 24 |
| 3, 5, 7 | 105 |
| 6, 9, 12 | 36 |
| 10, 15, 20 | 60 |
| 7, 14, 21 | 42 |
| 9, 18, 27 | 54 |
| 12, 24, 36 | 72 |
