While I was studying the properties of perfect square numbers, I came across an observation about how some perfect square numbers were able to generate prime numbers when added to the previous or next perfect square. So please I would appreciate a review of it.
This Artificial Intelligence Course is curated to deliver the best results.I think I could have found a prime number generator algorithm, but still I am not very sure, maybe this is an already known property of perfect square numbers, maybe not, but it looks amazing and I would like to know it is look logical or not, or a counterexample if it is wrong.

I hope you understood how to write a prime number program in Python. With this, we have come to the end of our article. So a more efficient method is to test if n is divisible by 2 or 3, then to check through all the numbers of form 6k ± 1. This is because all integers can be expressed as (6k + i) for some integer k and for i = ?1, 0, 1, 2, 3, or 4 2 divides (6k + 0), (6k + 2), (6k + 4) and 3 divides (6k + 3).
Instead of checking till n, we can check till √n because a larger factor of n must be a multiple of smaller factor that has been already checked.There are different ways to optimize the prime number program in Python: If any divisor is found then we display that the “number is not a prime number” else we display that the “number is a prime number”. Here, you will divide the input number by all the numbers to see whether there are any positive divisors other than 1 and number itself. If we find any other number which divides, print that value.įind out our Python Training in Top Cities/Countries IndiaĪ prime number is always positive and it will be checked at the beginning of the program. To find a prime number in Python, you have to iterate the value from start to end using a for loop and for every number, if it is greater than 1, check if it divides n. are prime numbers as they do not have any other factors. What is a Prime Number?Ī positive integer greater than 1 which does not have other factors except 1 and the number itself is called a prime number. In this article, we will see how to write a prime number program in Python in the following sequence:
You can write a code in Python that will help you find all the prime numbers. A prime number is a natural number greater than 1 and it does not have any divisor other than 1 and itself.
