This app can tell you if a number between 0 and 20000 is prime or not. It can also determine all divisors of any number less than 10000000. Fancy a game? Then you can try the quiz and collect points. Siri Shortcuts are also supported: You can also use your shortcuts to check whether your number is a prime number or not. Another shortcut can give you all the prime numbers from 0 to your entered number in a list. A shortcut can be used to determine all divisors of any number less than 100000, so the shortcut doesn't take too long.
