Frequently asked questions
What is the least common multiple?
The LCM is the smallest positive whole number that is exactly divisible by every number in the set.
Can I calculate the LCM of more than two numbers?
Yes. Enter several positive integers separated by commas or spaces, and the calculator combines them one pair at a time.
Is the LCM always larger than the entered numbers?
Not always. When one number is already a multiple of all the others, that number is the LCM.
