NAME

       factor - obtain the prime factors of a number

SYNOPSIS

       factor [integer]

DESCRIPTION

       factor  writes to standard input all prime factors for any positive integer less than or equal to 10**14. The prime factors are written the
       proper number of times.

       If factor is used without an argument, it waits for an integer to be entered. After entry of the integer, it factors it, writes	its  prime
       factors the proper number of times, and then waits for another integer. factor exits if a 0 or any non-numeric character is entered.

       If factor is invoked with an argument (integer), it writes the integer, factors it and writes all the prime factors as described above, and
       then exits. If the argument is 0 or non-numeric, factor writes a 0 and then exits.

       The maximum time to factor an integer is proportional to sqrt(n), where n is the integer which is entered. factor will take this time  when
       n is prime or the square of a prime.

OPERANDS

       integer	       Any positive integer less than or equal to 10**14.

EXIT STATUS

       0	Successful completion.

       1	An error occurred.

DIAGNOSTICS

       factor prints the error message Ouch! for input out of range or for garbage input.
