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 or the square of a prime.  It takes 1 minute
                              13
     to factor a prime near 10  .
