40
Work Step by Step
The least common multiple (LCM) of a group of numbers is the smallest number that is divisible by all of the numbers in the group. In order to find the LCM of 8 and 10, we can write the multiples of both numbers and find the first multiple that both numbers have in common.
8- 8, 16, 24, 32, 40
10 - 10, 20, 30, 40
Therefore, the LCM of 8 and 10 is 40.
