Finding the LCM of a longer list

For a long list, find the LCM of the first two numbers, then find the LCM of that result and the third number, and so on. Each step only ever deals with two numbers.

LCM(2, 3, 4, 5, 6)
LCM(2, 3) = 6
LCM(6, 4) = 12
LCM(12, 5) = 60
LCM(60, 6) = 60

A handy fact

The LCM of all the numbers from 1 to 10 is 2,520. That is why 2,520 shows up in puzzles about numbers that divide evenly by everything up to 10.
