What is the least common multiple (LCM) of 4 and 6?

To determine the least common multiple (LCM) of two numbers, we look for the smallest multiple that both numbers share. In this case, we want to find the LCM of 4 and 6.

First, we list the multiples of each number:

• The multiples of 4 are: 4, 8, 12, 16, 20, 24, ...
• The multiples of 6 are: 6, 12, 18, 24, ...

Next, we identify the common multiples from these lists. The first multiple that appears in both lists is 12. Since the LCM is defined as the smallest number that is a multiple of both numbers, 12 is indeed the least common multiple of 4 and 6.

Thus, the correct answer is the least common multiple: 12.
