Open calculatorThe LCM of two or more non-zero integers is the smallest positive integer that is divisible by all of the given numbers without a remainder.
The LCM of three or more numbers is found sequentially: LCM(a, b, c) = LCM(LCM(a, b), c).
LCM calculations are fundamental when adding fractions with differing denominators, synchronizing periodic timing cycles (such as traffic lights or planetary orbits), and scheduling repetitive events.
