- 412 is a composite number.
- Prime factorization: 412 = 2 x 2 x 103, which can be written 412 = (2^2) x 103
- The exponents in the prime factorization are 2 and 1. Adding one to each and multiplying we get (2 + 1)(1 + 1) = 3 x 2 = 6. Therefore 412 has exactly 6 factors.
- Factors of 412: 1, 2, 4, 103, 206, 412
- Factor pairs: 412 = 1 x 412, 2 x 206, or 4 x 103
- Taking the factor pair with the largest square number factor, we get √412 = (√4)(√103) = 2√103 ≈ 20.2978
