1. The problem asks to find all factors of 11. 2. A factor of a number is an integer that divides the number exactly without leaving a remainder. 3. Since 11 is a prime number, its only factors are 1 and 11. 4. To verify, divide 11 by each number from 1 to 11: $$\frac{11}{1} = 11 \quad \text{(no remainder)}$$ $$\frac{11}{11} = 1 \quad \text{(no remainder)}$$ 5. For any other number between 2 and 10, division will leave a remainder, so they are not factors. 6. Therefore, the factors of 11 are 1 and 11.
