What is the main purpose of numere-prime.ro

The website numere-prime.ro aims to provide users with some free reliable tools that automatically perform operations related to the prime factors or the numbers' parity, followed by extensive explanations, step by step. These tools can be used both as to perform the above operations fast, in order to save time, but also as an online learning / checking tool.

Why this website?

In 2012 I wrote a short article about the prime numbers in the section of the "known facts" of haios.ro website. This short article contained a list of the prime numbers up to 200. I noticed that the site visitors were very interested in this topic, of the prime numbers.

Here's a link to this article, containing a list of the prime numbers up to 200, in the section of haios.ro known facts (Romanian language): list of prime numbers up to 200. From here to the idea of creating a website that automatically performs various operations based on the prime numbers (prime factorization algorithm) wasn't a much longer way: numbere-prime.ro
