How to Check if a Number Is Prime

There are several methods for testing primality of integers. The best choice depends on the circumstances.

The faster methods are primality tests, not factorization algorithms, so even if they show a number to be composite, they reveal nothing about its prime factors. This article will help you to explore a few of the methods.

Windows Repair, Troubleshoot Windows Issues

When you are using Windows regularly, you likely run into issues eventually. This can be easy to fix stuff like running out of disk space or broken shortcuts to more serious problems like a virus infection or programs that won’t start up anymore. The troubleshooting and repair depends largely on the issue that is experienced on the computer system. If you suspect a virus you’d run up to date antivirus software, if a program does not run anymore you might be tempted to use System Restore or re-install the program to see if it fixes the issue.
