268 and Level 1

  • 268 is a composite number.
  • Prime factorization: 268 = 2 x 2 x 67, which can be written (2^2) x 67
  • 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 268 has 6 factors.
  • Factors of 268: 1, 2, 4, 67, 134, 268
  • Factor pairs: 268 = 1 x 268, 2 x 134, or 4 x 67
  • Taking the factor pair with the largest square number factor, we get √268 = (√4)(√67) = 2√67 ≈ 16.371.
