Answer: 8Step-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 41 Γ 4 β 42 Γ 4 β 83 Γ 4 β 124 Γ 4 β 16Notice that we skipped 0 Γ 6 in our list of multiples and this is because 0 Γ 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 81 Γ 8 = 8 β is a multiple of 4Notice 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.
