Apr 10, 2025 · Given a positive integer N, the task is to write a Python program to check if the number is Prime or not in Python. For example, given a number 29, it has no divisors other than 1 and 29 itself. Hence, it is a prime number. Note: Negative numbers (e.g. -13) …

In this example, you will learn to check whether an integer entered by the user is a prime number or not with 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

# Program to check if a number is prime or not num = 29 # To take input from the user #num = int(input("Enter a number: ")) # define a flag variable flag = False if num == 0 or num == 1: print(num, "is not a prime number") elif num > 1: # check for factors for i in range(2, num): if (num % i) == 0: # if factor is found, set flag to True flag ...

Oct 3, 2019 · Given a positive integer N. The task is to write a Python program to check if the number is prime or not. Definition: A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. The first few prime numbers are …

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.

Feb 10, 2025 · In this tutorial, we will learn how to write a program in C, C++, Python, and Java languages to check whether the entered number is a prime number or not. To write this program, the following are the prerequisites: What is a Prime Number? A natural number is called a prime number if it is only divisible by 1 and itself.

Mar 30, 2023 · Here I will discuss a Python program that finds whether a given number is a prime number or composite number or neither of them. Definition : A number greater than 1 is said to be prime if it has no other factors other than 1 and itself.

Apr 7, 2020 · The % operator gives you the remainder of an int division (ex. 5%2 = 1). Hence for a prime number there should always be a remainder, since no perfect division should be possible in the specified range. If there is no remainder then the code breaks the loop and classifies this number as not prime.

Here you will find the algorithm and program to check whether a number is prime or not with explanation. Step 1 → Take integer variable A. Step 2 → Divide the variable A with (A/2 to 2) Step 3 → If A is divisible by any value (A/2 to 2) then it is not prime. Step 4 → Else it is prime number.
