To find the least common multiple, LCM, of any two (or more) numbers, we simply factor each of them into the product of primes. Then, the LCM of the two (or more) numbers is the product of as many of those prime factors as are needed to reproduce each of the original numbers.

The LCM of numbers is found by listing down multiples of each number in the set. The first multiple to appear in both lists is taken to be the LCM of the set. It is explained in the example below. Start by listing the multiples of both 4 and 6.

Alternatively, the lcm of 35 and 91 can be found using the prime factorization of 35 and 91: The prime factorization of 35 is: 5 x 7. The prime factorization of 91 is: 7 x 13. Eliminate the duplicate factors of the two lists, then multiply them once with the remaining factors of the lists to get lcm(35,35) = 455.

The Least Common Multiple (LCM) of some numbers is the smallest number that the numbers are factors of. Like the LCM of 3 and 4 is 12, because 12 is the smallest number that 3 and 4 are both factors for. Type some numbers into the box to the right, and this page will find the LCM of those numbers.

Alternatively, the lcm of 13 and 14 can be found using the prime factorization of 13 and 14: The prime factorization of 13 is: 13. The prime factorization of 14 is: 2 x 7. Eliminate the duplicate factors of the two lists, then multiply them once with the remaining factors of the lists to get lcm(13,13) = 182.

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.
