#### What is the lowest common multiple?

The smallest common multiple of two or more numbers is called the lowest common multiple (LCM). E.g. Multiples of 8 are 8, 16, 24, 32, Multiples of 3 are 3, 6, 9, 12, 15, 18, 21, 24,

**How do you calculate least common multiple?**

One way to find the least common multiple of two numbers is to first list the prime factors of each number. Then multiply each factor the greatest number of times it occurs in either number. If the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.

**What is the LCM of 10 12 15?**

The least common multiple of 10, 12 and 15 is 60. The least common multiple (LCM) can be used to add or subtract unlike fractions, or fractions with different denominators, by helping to find the lowest common denominator.

## How do you find the LCM of a number?

To find the LCM of a set of numbers, take each number in the set and jot down a list of the first several multiples in order. The LCM is the first number that appears on every list.
