To calculate the least common multiple enter the numbers in the fields below and press calculate:
The Least Common Multiple (LCM) is the smallest number that is a multiple of two or more numbers. In other words, it is the smallest number that can be divided by another without leaving a remainder.
For example, the least common multiple of 12 and 15 is 60 because 60 is the smallest number divisible by 12 and 15. This means that 60 is the smallest number that can represent 12 and 15.
MMC is useful in many areas of mathematics, such as number theory, modular arithmetic, and geometry. It is also important in practical applications such as calculating the common frequency of periodic events and determining the length of the shortest common period of different events.
To calculate the LCM of two or more numbers by prime factors, you first need to find the list of prime factors for each number. You then compare the lists and multiply the common factors by the greatest number of times.
Follow the steps below to calculate the LCM of two numbers "a" and "b":
