How to find the Factors of 2

  • 2 is a prime number.
  • Prime factorization: 2 is prime.
  • The exponent in the prime factorization is 1. Adding one to that exponent we get (1 + 1) = 2. Therefore 2 has exactly 2 factors.
  • The factors of 2 are: 1 and 2
  • Factor pairs of 2 are: 1x2
  • 2 has no exponents greater than 1 in its prime factorization, so √2 cannot be simplified.
