LCM Calculator
Find the least common multiple for two or more positive integers with pairwise GCD steps and prime factorization.
Least common multiple with steps
LCM calculator intent in English often includes fraction work, least common denominator wording, and step-by-step methods such as listing multiples, prime factorization, or using the GCD formula.
The GCD removes the repeated common factor before multiplication.
- Enter two or more positive integers.
- Use pairwise GCD steps for a compact calculation path.
- Use prime factorization to confirm the highest exponent of each prime.
LCM and common denominators
The LCM is the smallest positive number divisible by every input. In fraction arithmetic, the LCM of denominators is the least common denominator.
| Input | LCM |
|---|---|
| 6, 8, 10 | 120 |
| 12, 18 | 36 |
| 15, 20, 30 | 60 |
