Calculate the Least Common Multiple (LCM) of two or more numbers. Shows prime factorisation and step-by-step solution.
Enter up to 10 integers separated by commas.
The Least Common Multiple (LCM) of two or more integers is the smallest positive integer that is divisible by each of them.
Prime Factorisation: Factor each number into primes. Take the highest power of each prime that appears. Multiply these together.
Example: LCM(12, 18) — 12 = 2²×3, 18 = 2×3². LCM = 2²×3² = 4×9 = 36.
LCM is used to add fractions with different denominators, schedule events that repeat at different intervals, and in number theory problems.
