Answers to Questions
How to calculate the next prime number?
There is no formula to find the next prime number. dCode uses an algorithm that performs a primality test on each of the numbers greater than or equal to the number requested.
Example: The first prime number following 1000 is 1009.
Example: The 10th prime number after 100 is 149 (so there are 9 prime numbers between 101 and 148)
The number must be a positive real number (the decimal numbers are accepted).
How to find smallest primes with n digits ?
The first prime number following \( 10^(n-1) \) is a number with \( n \) digits which is the smallest n-digit prime number.
Example: 2, 11, 101, 1009, 10007, etc.
What are twin primes numbers?
A prime number and the next prime number are said to be twins if their difference is 2.
Example: 11 and 13 are twins primes because 13-11 = 2.
