Prime Number Properties
Primes are the "atoms" of arithmetic. There are infinitely many of them, but they become increasingly rare as numbers grow.
Why are primes important in computing?
- RSA, the most widely used public-key algorithm, bases its security on the difficulty of factoring the product of two large primes (hundreds of digits).
- The Prime Number Theorem describes their distribution: about n/ln(n) primes below n. For n=1000: ~145 primes.
Examples
Twin prime
- Input
- 11 e 13
- Expected output
- ambos primos, diferença=2
Twin primes differ by 2.

A prime number is an integer greater than 1 that has no positive integer divisors other than 1 and itself. The first primes are 2, 3, 5, 7, 11, 13…
Frequently asked questions
Is there a largest prime?
No. Euclid proved there are infinitely many primes (~300 BC). The largest known primes today have millions of digits and are of the form 2ᵖ − 1 (Mersenne).
