- Prime factorisation
- 74 = 2 × 37
- Is 74 prime?
- No. It has 4 factors, not just 1 and 74.
- Is 74 a square number?
- No. 8 × 8 = 64 and 9 × 9 = 81, so 74 falls between two square numbers.
How to find the factors of 74
74 is even, so 2 is sure to be a factor. Work up from 1 to 8, and write down both numbers in every pair you find.
- 74 ÷ 1 = 74, so 1 × 74 is a pair.
- 74 ÷ 2 = 37, so 2 × 37 is a pair.
- 3 does not go into 74 exactly.
- 4 does not go into 74 exactly.
- 5 does not go into 74 exactly.
- 6 does not go into 74 exactly.
- 7 does not go into 74 exactly.
- 8 does not go into 74 exactly.
Stop at 9: 9 × 9 = 81, which is more than 74. The next pair you would find is 37 × 2, which is 2 × 37 turned round, so you already have every pair.
