To find the LCM of numbers you first need to break them down into their prime factors. In this case: 27=3x3x3 45=5x3x3 81=3x3x3x3 The next step is to disregard any duplicates when there are common prime factors. All numbers use two 3s so we can disregard 4 of them. Two numbers use an additional 3 so we can disregard 1 of them. This leaves us with: 5,3,3,3,3 Find the product of all of these numbers: 5x3x3x3=405 And that gives us the LCM. So the LCM of 27, 45, and 81 is 405.
