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.
