How to find the factors of 29
29 is prime, so the only pair you will find is 1 × 29. Work up from 1 to 5, and write down both numbers in every pair you find.
- 29 ÷ 1 = 29, so 1 × 29 is a pair.
- 2 does not go into 29 exactly.
- 3 does not go into 29 exactly.
- 4 does not go into 29 exactly.
- 5 does not go into 29 exactly.
Stop at 6: 6 × 6 = 36, which is more than 29. The next pair you would find is 29 × 1, which is 1 × 29 turned round, so you already have every pair.
