NAME
     factor - prints the prime factor of a given number

SYNOPSIS
     factor [number]

ARGUMENTS
     number
          Specifies the number from which factor will print its
          prime factors.

DESCRIPTION
     factor prints the prime factors of its argument.  When
     factor is invoked without an argument, it waits for a number
     to be typed in.  If you type in a positive number less than
     pow(2,56), it will factor the number and print its prime
     factors; each one is printed the proper number of times.
     Then it waits for another number.  It exits if it encounters
     a zero or any non-numeric character.

     If factor is invoked with an argument, it factors the number
     as above and then exits.

     Maximum time to factor is proportional to sqrt(n) and occurs
     when n is prime or the square of a prime, where n is the
     number being factored.  It takes 1 minute to factor a prime
            11
     near 10   on a 68020.

STATUS MESSAGES AND VALUES
     The message:

        Ouch

     is echoed when input is out of range or is garbage.
