What is the least common multiple of 4 and 8

Answer: 8

Step-by-step explanation: To find the least common multiple or (lcm) of 4 and 8, let's begin by listing the first few multiples of each number.

Multiples of 4

1 * 4 ≈ 4

2 * 4 ≈ 8

3 * 4 ≈ 12

4 * 4 ≈ 16

Notice that we skipped 0 * 6 in our list of multiples and this is because 0 * 4 is equal to 0 and our least common multiple can't be 0.

Now, let's list the multiples of 8. When listing the multiples of 8, it's a good idea to keep an eye on the list of multiples for 4 so that we will notice when we find a least common multiple.

Multiples for 8

1 * 8 = 8 ← is a multiple of 4

Notice that we can stop here because all other multiples that we find will be greater than 8. Therefore, the least common multiple or (lcm) of 4 and 8 is 8.
