   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.
