The question asks for the least common multiple (LCM) of 18, 29, and 27.

To find the LCM of these numbers, follow these steps:

1. **Prime Factorization**:
   - \( 18 = 2 \times 3^2 \)
   - \( 29 \) is a prime number.
   - \( 27 = 3^3 \)

2. **Determine the highest powers of each prime factor**:
   - For 2: the highest power is \( 2^1 \) (from 18).
   - For 3: the highest power is \( 3^3 \) (from 27).
   - For 29: the highest power is \( 29^1 \) (since 29 is prime).

3. **Multiply the highest powers together**:
   - \( LCM = 2^1 \times 3^3 \times 29^1 \)
   - \( = 2 \times 27 \times 29 \)
   - \( = 2 \times 783 = 1566 \)

So, the least common multiple of 18, 29, and 27 is **1566**.
