The least common multiple is the smallest positive number that is a multiple of two or more numbers.

2: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40

5: 5, 10, 15, 20, 25, 30, 35, 40

The easiest way to calculate an LCM is by breaking things down into prime numbers.

2 is already a prime.

5 is already a prime.

8=2x2x2

We then multiply the largest groupings of numbers. The largest grouping of 2s is in the 8 and the largest grouping of 5s is in the, well, 5. Thus, 2x2x2x5=40.

And so we see that the LCM is 40.
