FACTOR(6) BSD Games Manual FACTOR(6)NAMEfactor — factor a number
SYNOPSISfactor [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.
BUGSfactor cannot handle the “10 most wanted” factor list.
