>DESCRIPTION</a></h1>
<p>The factor utility will factor positive integers less than or equal to <code lang='und' xml:lang='und'>2^32 - 1</code>.
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.</p>
<p>When factor is invoked with one or more arguments,
each argument will be factored.</p>
<p>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 <code lang='und' xml:lang='und'>-</code> or <code lang='und' xml:lang='und'>+</code>.
Numbers are terminated by a non-digit character (such as a new-line).
After a number is read,
it is factored.</p>
