Description
Attn. NEWER MODEL P18 (UP TO 18-DIGITS) AVAILABLE: https://play.google.com/store/apps/details?id=biz.infosoft.prime18OVERVIEW
A Prime Number is a natural (a.k.a. counting) number that has exactly two distinct divisors (factors): number 1 and itself, called trivial factors. Any other factors are considered non-trivial and any natural number other than Prime is a composite number (number 1 is neither prime nor composite). Prime Factorization is about finding not-trivial factors of a natural number if they exist; otherwise, it is a Prime number.
For e.g., number 6 has two non-trivial factors: 2 and 3 (in other words, 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 numbers 2, 3 and 5 do not have any non-trivial factors: they are evenly divisible 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).
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
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.
Calculator is capable of processing large numbers up to 15 digits. Be aware that calculation of such big numbers may take several seconds, depends on how fast is the cellphone CPU (processor) - for more details see the following Benchmarks chapter
PLATFORMS
This app can run in any Cellphone or Tablet equipped with Android 5 or higher (i.e. Android Lollipop / Marshmallow / Nougat / Oreo). Prime factoring algorithm implements heavy "number crunching", so the computation time for large 15-digits Prime numbers could be in the range of seconds, depends of the computation power of the hardware.
Benchmarks
The factoring of the large Prime numbers (see the Reference) may serve as a basic "benchmark" reflecting the number crunching capability of your hardware (cellphone or tablet). For example, taking the largest 15-Digit Prime number: 999999999999989 and testing it on 3 different Android hardware platforms, the calculation time estimates:
Cellphones
1. Huawei Honor 5x (KIW-L24 / Android 6.0.1, API 23) - approx: 1 sec
2. Motorola Moto G (5) Plus (Android 7.0 API 24) - calculation time approx: 3 sec
Tablet
3. Samsung Galaxy Tab 7 (SM-T280 /Android 5.1.1, API 22) - approx: 10 sec
Clearly, the relatively new cellphones (1, 2) perform the Prime "number crunching" much faster than the old version of Samsung Galaxy Tab 7.

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.
