Find the least common multiple of two or more integers.
LCM from page inputsUses the live LCM method for the entered integers.
This LCM calculator finds the least common multiple of the integers on the page. Use it for adding fractions or aligning repeating schedules.
GCF and LCM relate through product identities for two positive integers. Compute GCF with the GCF calculator and compare factor lists on the common factor calculator.
a=12, b=18, c=0 returns LCM 36.
The optional third number is unused, so the tool returns LCM(12, 18) only.
LCM(a,b) = |a*b| / GCF(a,b). For 12 and 18, GCF is 6, so |216|/6 = 36.
For positive integers it is at least as large as each input. It equals a number when one divides the other.
Yes. Use the GCF calculator to inspect the divisor step beside this LCM page.
Yes. Take highest powers of shared primes. A factor calculator helps list building blocks.
LCM is usually discussed for positive integers. Absolute values keep the product step well defined in the formula shown.
Adding fractions with unlike denominators and scheduling problems that repeat on cycles both use LCM ideas.
