SYNTAX
factor [ number ]
DESCRIPTION
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 1014
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.
