The LCM of 17, 27, and 54 is 54.

To solve, write each of the numbers in their prime factorization in power form and then multiply together the value of the highest power of all the primes across all the numbers.

18 = 2 x 3^2

27 = 3^3

54 = 2 x 3^3

Highest power of each prime is: 2 and 3^3, so the LCM = 2 x 3^3 = 54.
