FACTOR(6)		     FreeBSD Games Manual		     FACTOR(6)

NAME
     factor, primes -- factor a	number,	generate primes

SYNOPSIS
     factor [-h] [number ...]
     primes [-h] [start	[stop]]

DESCRIPTION
     The factor	utility	will factor positive integers.	When a number is fac-
     tored, it is printed, followed by a `:', and the list of factors on a
     single line.  Factors are listed in ascending order, and are preceded by
     a space.  If a factor divides a value more	than once, it will be printed
     more than once.

     When factor is invoked with one or	more arguments,	each argument will be
     factored.

     When factor is invoked with no arguments, factor reads numbers, one per
     line, from	standard input,	until end of file or error.  Leading white-
     space and empty lines are ignored.	 Numbers may be	preceded by a single
     `+'.  Numbers are terminated by a non-digit character (such as a new-
     line).  After a number is read, it	is factored.

     The primes	utility	prints primes in ascending order, one per line,	start-
     ing at or above start and continuing until, but not including stop.  The
     start value must be at least 0 and	not greater than stop.	The stop value
     must not be greater than the maximum.  The	default	and maximum value of
     stop is 4294967295	on 32-bit architectures	and 18446744073709551615 on
     64-bit ones.

     When the primes utility is	invoked	with no	arguments, start is read from
     standard input and	stop is	taken to be the	maximum.  The start value may
     be	preceded by a single `+'.  The start value is terminated by a non-
     digit character (such as a	newline).

DIAGNOSTICS
     negative numbers aren't permitted
     illegal numeric format
     start value must be less than stop	value
     Result too	large

BUGS
     factor cannot handle the ``10 most	wanted'' factor	list, primes will not
     get you a world record.
