• 596 is a composite number.
• Prime factorization: 596 = 2 x 2 x 149, which can be written 596 = (2^2) x 149
• The exponents in the prime factorization are 1 and 2. Adding one to each and multiplying we get (1 + 1)(2 + 1) = 2 x 3  = 6. Therefore 596 has exactly 6 factors.
• Factors of 596: 1, 2, 4, 149, 298, 596
• Factor pairs: 596 = 1 x 596, 2 x 298, or 4 x 149
• Taking the factor pair with the largest square number factor, we get √596 = (√4)(√149) = 2√149 ≈ 24.41311123
