### How to find prime numbers?

To know if a number is prime, it is necessary to pass primality test. A test that will verify mathematically and algorithmically, that the number is divisible by none other than itself.

Example: 10 is divisible by 2 so is not prime

Example: 11 is not divisible by 2, 3, 4, 5, 6, 7, 8, 9, or 10, so it's a prime.

There is no method (other than testing all numbers) to find a list of prime numbers exhaustively and quickly.

### How do I find the next or previous prime number?

Again, it has no foolproof technique, dCode will detect the first number (upper or lower) that will be a prime number.
