1. The problem is to find the factors of 12. 2. Factors of a number are integers that divide the number exactly without leaving a remainder. 3. To find factors of 12, we check all integers from 1 to 12 and see which divide 12 evenly. 4. Start with 1: $12 \div 1 = 12$ (no remainder), so 1 is a factor. 5. Check 2: $12 \div 2 = 6$ (no remainder), so 2 is a factor. 6. Check 3: $12 \div 3 = 4$ (no remainder), so 3 is a factor. 7. Check 4: $12 \div 4 = 3$ (no remainder), so 4 is a factor. 8. Check 5: $12 \div 5 = 2.4$ (remainder), so 5 is not a factor. 9. Check 6: $12 \div 6 = 2$ (no remainder), so 6 is a factor. 10. Check 7 to 11: none divide 12 evenly. 11. Check 12: $12 \div 12 = 1$ (no remainder), so 12 is a factor. 12. Therefore, the factors of 12 are $1, 2, 3, 4, 6, 12$.
