What are prime numbers in maths? If you are having trouble with mathematics, we will try to give you the explanation of prime numbers. We hope it will be helpful. The prime numbers are also known as natural numbers. These numbers have two different divisors that are also natural numbers and those divisors are number 1 and the given prime number itself.

In other words, a prime number can be divided with 1 or with itself. Some of the prime numbers are 2, 13, 17, 31, 97 etc. These are just some of the examples, but there are many prime numbers. Actually there are so many of them that it would be impossible to enumerate them even if we tried. This is so because they are infinite. This fact was proven by Euclid, somewhere around 300 BC.

Since the prime numbers are infinite, sometimes it can be hard to prove the primality of a very large number. When it comes to prime number that are smaller than 100, their primalities are rather obvious and may be proven with no special effort. But in large numbers, the things are little different. In order to prove that a number really is a prime number, and to do that in more efficient way, experts have developed several procedures. There are rather sophisticated and reliable algorithms that make this proving process easier.

There are many theories about prime numbers. Some of those are still unclear and yet to be solved. But regardless to those things we do not know – we can still rely on what we know and use it! And this is exactly the case with prime numbers. They are used in the wide field of the information technologies. We hope that this article contributed to your comprehension of prime numbers.
