Prime factors of 88
- Prime factorisation
- 88 = 2 × 2 × 2 × 11 (2³ × 11)
- Reading index form
- A small raised number tells you how many times to use that factor. For example, 2³ means 2 × 2 × 2.
- Is 88 prime?
- No. It has 8 factors, not just 1 and 88.
- Is 88 a square number?
- No. 9 × 9 = 81 and 10 × 10 = 100, so 88 falls between two square numbers.
How to find the factors of 88
88 is even, so 2 is sure to be a factor. Work up from 1 to 9, and write down both numbers in every pair you find.
- 88 ÷ 1 = 88, so 1 × 88 is a pair.
- 88 ÷ 2 = 44, so 2 × 44 is a pair.
- 3 does not go into 88 exactly.
- 88 ÷ 4 = 22, so 4 × 22 is a pair.
- 5 does not go into 88 exactly.
- 6 does not go into 88 exactly.
- 7 does not go into 88 exactly.
- 88 ÷ 8 = 11, so 8 × 11 is a pair.
- 9 does not go into 88 exactly.
Stop at 10: 10 × 10 = 100, which is more than 88. The next pair you would find is 11 × 8, which is 8 × 11 turned round, so you already have every pair.
