          FACTOR(1)            INTERACTIVE UNIX System            FACTOR(1)



          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.
