What is the LCM of 4 and 6?

12

Step-by-step explanation:

The least common multiple (LCM) is the lowest (least) postive number that two or more numbers can be divided into without a remainder. To find it, you can list the multiples, in order, of the given numbers. For 6, you would list {6, 12 , 18, 24...}. For 4, you would list {4, 8, 12 , 16, 20, 24...}. Then you look for the lowest positive number that these two sets share. In this case, it is 12. As you can see, 12 is the first number which appears in each set. The number 24 is also shared, but it is not the first common multiple, so the answer is 12.
