How do you find the next prime number?
There is no formula on how to find the next prime number. dCode uses an algorithm that performs a probabilistic primality test (Miller-Rabin test) on each of the numbers greater than or equal to the number requested, then check it with a deterministic test. Example: The first prime number following 1000 is 1009.
Is there a list of all prime numbers?
List of Prime Numbers Sequence Prime Number 1 2 2 3 3 5 4 7
