FACTOR(VI) 1/15/73 FACTOR(VI) NAME factor - discover prime factors of a number SYNOPSIS factor DESCRIPTION When factor is invoked, it types out `Enter:' at you. If 56 you type in a positive number less than 2 (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 delete. Maximum time to factor is proportional to sqrt(n) and occurs when n is prime. It takes 1 minute to factor a prime near 13 10 . DIAGNOSTICS `Ouch.' for input out of range or for garbage input. BUGS
