Prime factors of 76
- Prime factorisation
- 76 = 2 × 2 × 19 (2² × 19)
- Reading index form
- A small raised number tells you how many times to use that factor. For example, 2³ means 2 × 2 × 2.
- Is 76 prime?
- No. It has 6 factors, not just 1 and 76.
- Is 76 a square number?
- No. 8 × 8 = 64 and 9 × 9 = 81, so 76 falls between two square numbers.
How to find the factors of 76
76 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.
- 76 ÷ 1 = 76, so 1 × 76 is a pair.
- 76 ÷ 2 = 38, so 2 × 38 is a pair.
- 3 does not go into 76 exactly.
- 76 ÷ 4 = 19, so 4 × 19 is a pair.
- 5 does not go into 76 exactly.
- 6 does not go into 76 exactly.
- 7 does not go into 76 exactly.
- 8 does not go into 76 exactly.
Stop at 9: 9 × 9 = 81, which is more than 76. The next pair you would find is 19 × 4, which is 4 × 19 turned round, so you already have every pair.
