How to find the Factors of 8
- 8 is a composite number.
- Prime factorization: 8 = 2x2x2, which can be written 8 = 23
- The exponents in the prime factorization are 3. Adding one to each exponent and multiplying we get (3 + 1) = 4 = 4. Therefore 8 has exactly 4 factors.
- The factors of 8 are: 1, 2, 4 and 8
- Factor pairs of 8 are: 1x8 and 2x4
- 8 has at least one exponent greater than 1 in its prime factorization so √8 can be simplified. Taking this into account, we get √8 = 2x√2
