NAME
      factor - obtain the prime factors of a number

SYNOPSIS
      factor [integer]

DESCRIPTION
      When you use factor without an argument, it waits for you to give it an
      integer.  After you give it a positive integer less than or equal to
      1014, it factors the integer, prints its prime factors the proper number
      of times, and then waits for another integer.  factor exits if it
      encounters a zero or any non-numeric character.

      If you invoke factor with an argument, it factors the integer as
      described above, and then it exits.

      The maximum time to factor an integer is proportional to sqrt(n), factor
      will take this time when n is prime or the square of a prime.

DIAGNOSTICS
      factor prints the error message, Ouch, for input out of range or for
      garbage input.
