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 12 15 and 20?

The least common multiple is the product of all factors in the greatest number of their occurrence. The least common multiple of 12, 15 and 20 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 to figure out LCM?

List all the prime numbers found, as many times as they occur most often for any one given number. Multiply the list of prime factors together to find the LCM . The LCM (a,b) is calculated by finding the prime factorization of both a and b. Use the same process for the LCM of more than 2 numbers.
