FACTOR(6)                     NetBSD Games Manual                    FACTOR(6)

NAME
     factor -- factor a number

SYNOPSIS
     factor [number ...]

DESCRIPTION
     The factor utility will factor integers between -2147483648 and
     2147483647 inclusive.  When a number is factored, 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 -
     or +.  Numbers are terminated by a non-digit character (such as a new-
     line).  After a number is read, it is factored.  Input lines must not be
     longer than 255 characters.

DIAGNOSTICS
     Out of range or invalid input results in an appropriate error message
     being written to standard error.

BUGS
     factor cannot handle the ``10 most wanted'' factor list.
