<p>How do we describe prime numbers? It's quite simple. It is a number which is 1 and has only two factors. The only two factors are 1 and the number itself. These two factors can divide the number, leaving no reminder. In this topic, let us learn more about prime numbers.</p>

<p>This is a rather simple method where we write down all the prime numbers until we cross the required number, for example let's write down all the prime numbers from 1 to 1009. 2, 3, 5, 7…. 991, 997, 1009. From looking at the above list, we can see that 1009 is a prime number. </p>
