Mr. Rose, Mr. Stein, and Mr. Schwartz start at the same point around a circular track and run clockwise. Mr. Stein completes each lap in $6$ minutes, Mr. Rose in $10$ minutes, and Mr. Schwartz in $18$ minutes. How many minutes after the start of the race are the runners at identical points around the track (that is, they are aligned and are on the same side of the track) for the first time?
To determine when Mr. Rose, Mr. Stein, and Mr. Schwartz will be at the same point on the track for the first time, we need to find the least common multiple (LCM) of their lap times. The lap times are 6 minutes, 10 minutes, and 18 minutes respectively.

1. **Prime Factorization**:
   - Mr. Stein's lap time: \(6 = 2 \times 3\)
   - Mr. Rose's lap time: \(10 = 2 \times 5\)
   - Mr. Schwartz's lap time: \(18 = 2 \times 3^2\)

2. **Determine the LCM**:
   - The LCM is found by taking the highest power of each prime that appears in the factorizations.
   - For the prime number 2: the highest power is \(2^1\) (appears in all factorizations).
   - For the prime number 3: the highest power is \(3^2\) (appears in Mr. Schwartz's factorization).
   - For the prime number 5: the highest power is \(5^1\) (appears in Mr. Rose's factorization).

3. **Calculate the LCM**:
   \[
   \text{LCM} = 2^1 \times 3^2 \times 5^1 = 2 \times 9 \times 5 = 90
   \]

Thus, the least common multiple of 6, 10, and 18 is 90 minutes. This means that all three runners will be at the same point on the track after 90 minutes.

The final answer is \(\boxed{90}\) minutes.
