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.
