Answers to Questions (FAQ)

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 to detect the next prime or the previous prime, dCode will detect the first number (upper or lower) that will be a prime number.
