     NAME
          factor - factor a number

     SYNOPSIS
          factor [number]

     DESCRIPTION
          factor prints the prime factors of its argument.  When fac-
          tor 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
