Final answer:
The least common multiple (LCM) is the smallest multiple that two or more numbers have in common. It can be found by listing the multiples of each number or by using prime factorization.
Step-by-step explanation:
The least common multiple (LCM) is the smallest multiple that two or more numbers have in common. To find the LCM, you can list the multiples of each number until you find a common multiple. Another method is to use prime factorization. Find the prime factorization of each number and then multiply the highest powers of all the prime factors.
For example, if you need to find the LCM of 6 and 8, the multiples of 6 are 6, 12, 18, 24, ... and the multiples of 8 are 8, 16, 24, ... The least common multiple is 24.
