1. The problem is to identify the set of numbers given: 1, 2, 3, 6, -1, -2, -3, -6. 2. These numbers appear to be the divisors of a certain integer because they include both positive and negative values. 3. To verify this, check if all these numbers divide a certain integer evenly. 4. Notice that the positive numbers are 1, 2, 3, and 6, which are all divisors of 6. 5. Therefore, the full set of divisors including the negative counterparts is \(\pm1, \pm2, \pm3, \pm6\). 6. Hence, the answer represents the complete set of the divisors of 6, including negative divisors. Final answer: The given numbers are the positive and negative divisors of 6.
