FACTOR (I)                   1/15/73                   FACTOR (I)

NAME            factor -- discover prime factors of a number

SYNOPSIS        factor

DESCRIPTION     When factor is invoked, it types out "Enter:" at

                you.  If you type in a positive number less than

                2^56 (about 7.2E16), it will repeat the number

                back at you and then its prime factors each one

                printed the proper number of times.  Then it says

                "Enter:" again.  To exit, feed it an EOT or a


                Maximum time to factor is proportional to sqrt(n)

                and occurs when n is prime.  It takes 1 minute to

                factor a prime near 10^13.
