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.
The LCM is 840.
