To solve the problem of identifying the number that is different from the others, we will follow these steps:

### Step 1: List the given numbers
The numbers provided are: 17, 27, 29, and 37.

### Step 2: Identify the properties of the numbers
We need to analyze the properties of each number. We can check if they are odd or even, and whether they are prime or composite.

- **17**: Odd, Prime
- **27**: Odd, Composite (since it can be divided by 3)
- **29**: Odd, Prime
- **37**: Odd, Prime

### Step 3: Compare the properties
From our analysis:
