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 fac
tors it, writes its prime factors the proper number of
times, and then waits for another integer. factor exits if a
0 or any nonnumeric 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
nonnumeric, 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.
