factor(1)
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 10[14],
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
(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.
