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.

GCF = 27 LCM = 81 81 is the LCM of 27 and 81

To find the least common multiple (LCM) of 9, 45, and 81, we first need to factorize each number. The prime factorization of 9 is 3^2, 45 is 3^2 * 5, and 81 is 3^4. The LCM is the product of the highest power of each prime factor that appears in any of the numbers. Therefore, the LCM of 9, 45, and 81 is 3^4 * 5, which equals 405.

27 and 81, respectively.

The LCM is 405.
