Description
INTRODUCTIONA Prime Number is a natural (a.k.a. counting) number that has exactly two distinct divisors called trivial factors, namely: number 1 and itself. Any other factors are considered non-trivial. Any natural number other than Prime is a composite number. Composite numbers are made of their non-trivial factors - they equal to the product of said factors. Number 1 is neither prime nor composite.
OVERVIEW
Prime Factorization is a mathematical task of finding not-trivial factors of any given natural number; if they don't exist then the number under the test is a Prime number.
For example, number 6 has two non-trivial factors 2 and 3, therefore 6 = 2 * 3; number 15 also has two non-trivial factors 3 and 5 (15 = 3 * 5); number 100 has 4 non-trivial factors, namely: 2, 2, 5, 5, thus 100 = 2 * 2 * 5 * 5. On the other side, the Prime numbers 2, 3 and 5 do not have any non-trivial factors: they are evenly divisible (i.e. divisible without remainder) only by the number 1 and the number itself.
Note: in this notation the asterisk "*" means arithmetic multiplication, same as "x" symbol (they can be used interchangeably, thus it could be written: 6 = 2 x 3).
Summary: Prime Numbers do not have any non-trivial factors, like 3, 5, 7 11. Any number with two or more non-trivial factors is called a Composite number, like said number 6, or number 9 (9 = 3 * 3), or 10 (10 = 2 * 5), etc.
USAGE
Calculator is capable of processing large numbers up to 18 digits. To find the prime factors, enter the number in the text box using on-screen keypad and click on enter button "=". Result will appear on digital displaying, showing either the list of found prime factors, or the message indicating that input number is Prime.
PLATFORMS
This app can run in any Cellphone or Tablet equipped with Android 5 or higher.
ALGORITHM
The Calculator utilizes efficient parallel "Wheel Prime Factorization" algorithm optimized for octal-core processors capable of processing large 18-digits numbers in a split second. The actual computation efficiency depends on the platform. The app implements speed test that allows to evaluate device computational power pertinent to Prime factorization heavy number-crunching task. For the reference purpose, largest Prime numbers up to 18-digits are listed below.

Questions & Answers
Q: What is an APK File?
A: Just like Windows (PC) systems use an .exe file for installing software, Android does the same. An APK file is the file format used for installing software on the Android operating system.
Q: If I install an APK from this website, will I be able to update the app from the Play Store?
A: Yes, absolutely. The Play Store installs APKs it downloads from Google's servers, and sideloading from a site like ApkClean.net goes through a very similar process, except you're the one performing the downloading and initiating the installation (sideloading).
As soon as the Play Store finds a version of the app newer than the one you've sideloaded, it will commence an update.
Q: Why ApkClean.net can guarantee APK 100% safe?
A: Whenever someone wants to download an APK file from ApkClean.net, we'll check the corresponding APK file on Google Play and allow user download it directly (of course, we'll cache it on our server). If the APK file does not exist on Google Play, we'll search it in our cache.
Q: What are Android App permissions?
A: Apps require access to certain systems within your device. When you install an application, you are notified of all of the permissions required to run that application.
Don't hesitate to contact us if you have any questions or concerns.
