FACTOR(1)		    General Commands Manual		     FACTOR(1)

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

SYNOPSIS
       factor [	number ]

       primes [	start [	finish ] ]

DESCRIPTION
       Factor  prints  number  and its prime factors, each repeated the	proper
       number of times.	 The number must  be  positive	and  less  than	 2**54
       (about 1.8e16)

       If  no number is	given, factor reads a stream of	numbers	from the stan-
       dard input and factors them.  It	exits on any input not a positive  in-
       teger.  Maximum running time is proportional to sqrt(n).

       Primes  prints  the  prime  numbers ranging from	start to finish, where
       start and finish	are positive numbers less than 2**56.	If  finish  is
       missing,	 primes	 prints	without	end; if	start is missing, it reads the
       starting	number from the	standard input.
