How do you find the least common multiple of a set of numbers? How do you use least common multiple? How can you find the least common multiple using prime factorization?... For example, multiples of 2 are 2,4,6,8,10... and multiples of 5 are 5,10,15... If you notice, lowest common number is 10. The answer is 10. If there are no common numbers, the answer is always "1". If you notice, lowest common number is 10.
some common multiples of 4 and 6. The least common multiple (LCM) of a group of numbers is the smallest number that is a multiple of each number in the group.
The lcm of 5 and 6 is the smallest positive integer that divides the numbers 5 and 6 without a remainder. Spelled out, it is the least common multiple of 5 and 6.
