We can add and store it in a temporary variable if it is a prime number.
Step2: Then, we check if the given number is a prime or not. Step1: As we are looking to find the sum of prime numbers up to N, we first need to iterate through each number up to the given number. To find the prime numbers with python, please go through the article Prime Number Program in Python as this covers the basic to advanced level of how we can find the prime numbers in python along with few programs of optimizing that code.Īfter you have gone through the above article, let us discuss the algorithm we will follow to find the sum of prime numbers in python. Introductionīefore starting with the algorithm where we shall understand how to find the sum of all prime numbers between 1 to n, we should first briefly understand what prime numbers are.Ī prime number can be defined as a positive integer greater than 1 and only divisible by two numbers, 1 and itself. Some prime numbers include 2, 3, 5, 7, 11, 13, etc.Īnd the sum of prime numbers denotes the summation of all the prime numbers less than or equal to the given input. In other words, prime numbers are positive integers greater than 1 with exactly two factors, one and the number itself. Prime numbers are natural numbers that are divisible by only one and the number itself.
