Number of prime numbers

Prime Numbers Set Definition

Definition of prime numbers can be written all over as this: Prime numbers does not have a factor other than itself and 1; as following;

For ;
row value, column value which

Sets consists of 's are;


P shows prime numbers' set,

Some features of sets are like below,

Set A consists of positive integers starting from 1, set B consists of positive integers greater than 1. Separately multiplying their own members with their own thus getting a new pair of sets. The difference of the new sets is the set of almost prime numbers. 1 is not a member of the prime numbers' set, prime numbers' set could be obtained by substracting 1 from latest found set. If it's desired a N value could be selected by that prime numbers' set can be obtained within the range of 1 to N --Nexusiot (talk) 20:46, 2 June 2016 (UTC) Comment : "Please add this new feature" --Nexusiot (talk) 20:46, 2 June 2016 (UTC)

  2. This request is unclear exactly what needs to be changed or added. It would be easier to process this if you wrote this in a "Change X to Y" format. — Andy W. (talk ·ctb) 21:34, 2 June 2016 (UTC)

Prime number formula[edit]

All prime numbers have to follow this formula is: 6n±1 — Preceding unsigned comment added by (talk) 00:33, 5 October 2016 (UTC)

2 and 3 don't. Numbers of form 6n±1 is the same as numbers not divisible by 2 or 3 so it clearly includes all primes above 3. PrimeHunter (talk) 00:52, 5 October 2016 (UTC)

In the list of prime number you have 101 as a prime number, this is incorrect. — Preceding unsigned comment added by Theisencouple (talkcontribs)

101 is certainly a prime. See OEIS:A000040 or test it yourself. PrimeHunter (talk) 18:33, 19 November 2016 (UTC)
