Note
Some pieces of anti-malware software falsely labels software from individual developers as malware. If you faced this behavior on this software, restore it from the chest or allow it. You can check out the source code and build it yourself if you are not sure whether this software is safe.
Download an appropriate one from Releases and run it on your device. No installation needed. You can also uninstall this software just by removing the executable file itself, as it doesn't touch the system registry or such.
You will first see the "Prime Factorization" mode. Enter a natural number in the input box and press the OK button or the Enter key, to get the result.
You can switch to the "Enumerate Prime Numbers" mode in the Options menu. Specify a range to enumerate prime numbers and a max count within, and press the OK button or the Enter key to start. You can set to use a text file as the output destination, as the output box can only hold 65,535 or less characters.
You can use the File menu to export the contents in the output box to a text file or copy it to the clipboard. Also, you can use the top row (QWERTY...) keys to input numbers if your device does not have number keys.
