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 standard
     input and factors them.  It exits on any  input  not  a  positive	integer.
     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 num-
     ber from the standard input.
