716 and Level 6

  • 716 is a composite number.
  • Prime factorization: 716 = 2 x 2 x 179, which can be written 716 = (2^2) x 179
  • 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 716 has exactly 6 factors.
  • Factors of 716: 1, 2, 4, 179, 358, 716
  • Factor pairs: 716 = 1 x 716, 2 x 358, or 4 x 179
  • Taking the factor pair with the largest square number factor, we get √716 = (√4)(√179) = 2√179 ≈ 26.758176.
