## Quick Answer

Find the least common multiple (LCM) of two or more numbers. Enter your numbers to compute the smallest shared multiple and prime factorization work.

## Definition

An LCM calculator (Least Common Multiple) is a mathematical utility that finds the smallest positive integer that is a multiple of two or more numbers. The calculator evaluates the inputs using methods such as listing multiples, prime factorization, or the greatest common divisor formula. It outputs the least common multiple along with step-by-step math explanations for each calculation method. Students, teachers, and developers use this tool to find common denominators for fractions, solve scheduling problems, and analyze periodic events.

## How to Use

1. **Enter numbers** — Type the integers you want to evaluate, separated by commas or spaces.
2. **Select LCM method** — Choose between listing multiples, prime factorization, or the GCD formula method.
3. **View the LCM** — Read the least common multiple and review the mathematical steps showing the factorization work.
