• 328 is a composite number.
• Prime factorization: 328 = 2 x 2 x 2 x 41, which can be written (2^3) x 41
• 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 328 has exactly 8 factors.
• Factors of 328: 1, 2, 4, 8, 41, 82, 164, 328
• Factor pairs: 328 = 1 x 328, 2 x 164, 4 x 82, or 8 x 41
• Taking the factor pair with the largest square number factor, we get √328 = (√4)(√82) = 2√82 ≈ 18.111
