<div class="textblock"><p>A simple program to check if the given number is <a href="https://en.wikipedia.org/wiki/Primality_test" target="_blank">Prime</a> or not. </p>
<p>A prime number is any number that can be divided only by itself and 1. It must be positive and a whole number, therefore any prime number is part of the set of natural numbers. The majority of prime numbers are even numbers, with the exception of 2. This algorithm finds prime numbers using this information. additional ways to solve the prime check problem: <a href="https://cp-algorithms.com/algebra/primality_tests.html#practice-problems">https://cp-algorithms.com/algebra/primality_tests.html#practice-problems</a> </p><dl class="section author"><dt>Author</dt><dd><a href="https://github.com/omkarlanghe" target="_blank">Omkar Langhe</a> </dd>
