Program to check whether a number entered by user is prime or not in Python with output and explanation…

Jan 3, 2018 · In this post, we will write a program in Python to check whether the input number is prime or not. A number is said to be prime if it is only divisible by 1 and itself. For example 13 is a prime number because it is only divisible by 1 and 13, on the other hand 12 is not a prime number because it is divisible by 2, 4, 6 and number itself.

In this tutorial, you will learn to write a Python Program to Check Prime Number. A prime number is a positive integer greater than 1 that has no positive integer divisors other than 1 and itself. In other words, a prime number is a number that is only divisible by 1 and itself.

Oct 20, 2024 · To check if a number is prime in Python, you can use an optimized iterative method. First, check if the number is less than or equal to 1; if so, it’s not prime. Then, iterate from 2 to the square root of the number, checking for divisibility. If the number is divisible by any of these, it’s not prime; otherwise, it is.
