Primknacker

Genau das, was ich gesucht hatte, eine Primzahl-Prüfung und Primfaktorzerlegung und sogar eine Übersicht über einen Zahlenbereich! Top wäre jetzt noch die Nummer der Primzahl, d.h. die wievielte es ist, wäre eine schöne Erweiterung.

Nehme die App auch zum Zeitmessen beim kochen und grillen.

Just Blown Away to see this!

Great utility, very helpful.

This is a wonderful app for quickly finding out whether or not a given number is prime. I like how it even gives you all the possible factors of the number itself. I would highly recommend this app to anybody interested in learning about different types of numbers: Composite, Prime, etc.

Incredible primes explorer. Ultra fast, flexible, user friendly and the best prime number tool in the world for what it does and I’ve checked a lot of apps out. Ranges, enumeration, twins, validation check, what’s not to like! THANK YOU genius programmers, and as far as I can tell free full version

I used to spend way too much time cracking prime numbers manually. But then I found Prime Cracker! Thank you for giving me my life back, Prime Cracker!!!
