- 776 is a composite number.
- Prime factorization: 776 = 2 x 2 x 2 x 97, which can be written 776 = (2^3) x 97
- The exponents in the prime factorization are 3 and 1. Adding one to each and multiplying we get (3 + 1)(1 + 1) = 4 x 2 = 8. Therefore 776 has exactly 8 factors.
- Factors of 776: 1, 2, 4, 8, 97, 194, 388, 776
- Factor pairs: 776 = 1 x 776, 2 x 388, 4 x 194, or 8 x 97
- Taking the factor pair with the largest square number factor, we get √776 = (√4)(√194) = 2√194 ≈ 27.85677655
