1) Watch the list of prime numbers,
2) Highlight prime numbers among all natural numbers (from 1 to 10.000)!
3) Check whether your given number is a prime one! And, by the way, find all divisors of your given number!
This app is intended for all people who are interested in the topic of prime numbers, especially - for pupils, students and high-educated people!

In addition, the calculator calculates the GCF (Greatest Common Factor) and LCM (Least Common Multiple) of given numbers.

(Please note: the Big Integer Calculator, also by this developer, includes this prime factorization algorithm, along with other features.)
The app uses Pollard's Rho algorithm to find factors of large integers, in combination with trial division optimized for speed when possible by interpreting sub-factors as long integers.
A menu button allows factorization calculations to be extended for faster devices. Pollard's Rho calculations are iterated more times when the depth in increased, which results in factorizing 'harder' numbers, but takes longer. The depth can also be reduced.
The app will accept arbitrarily large integers, and will find the prime factors of powers of 10 or other numbers with small factors very quickly. For example, if you calculate 3000! using some big integer calculator, and paste this number into the prime factor app, it will find the complete factorization in around ten seconds (Galaxy S4).
Integers with prime factors of seven or more digits will take longer to factorize, depending on the device the app is running on.
Progress is shown by listing factors as they are found. If a sub-factor which is known to be non-prime is taking a long time to factorize, the display will show "working ...". Calculation can be cancelled by pressing the back button on the device. However, if the app cannot find all the factors, it will terminate and list any factors it has found, rather than hanging or freezing.
Use spaces, commas or new lines as delimiters for new numbers (how to separate different numbers from each other).
If your keyboard doesn't allow you to type spaces or commas, you'll have to download a different keyboard or use new lines to separate numbers.
Use the 'restore' button to restore the last data you entered before you closed the app the last time.
Long click on the display text, or the numbers you entered and it will bring up the option to copy or paste.
Switch between input screens for the classic GCF screen and the new, unlimited input GCF screen by clicking the options in the top right corner of the app. If you don't have the option in the top right corner, click your Menu BUTTON (which is a physical button on your phone).
Note: The greatest common divisor (gcd) of two or more non-zero integers, is the largest positive integer that divides the numbers without a remainder. For example, the greatest common divisor of 8 and 12 is 4. The greatest common divisor is useful for reducing fractions to be in lowest terms.
You will be thrown one number after the next, cut them up if they can be factored into smaller values, if not, if they are prime, do not cut them.
Prime numbers are numbers that cannot be divided into small whole numbers. One, two, three, five, seven, eleven, and thirteen are all examples of prime numbers. Four is not prime because it can be broken down in the whole numbers two times two.
