Web18 jan. 2024 · Write a Python program that uses the Sieve of Eratosthenes method to compute prime numbers up to a specified number. Note: In mathematics, the sieve of Eratosthenes (Ancient Greek: κόσκινον Ἐρατοσθένους, kóskinon Eratosthénous), one of a number of prime number sieves, is a simple, ancient algorithm for finding all prime … WebYou only need to loop to the square root of the number, because after that you'll just repeat the same numbers again. For example if you were testing for 100, after 10 you will find 20, but you already tested it while you were testing the 5, 100/5 = 20 and 100/20 = 5, if 5 didn't divide 100 so 20 won't and vice versa, so 100/a = b tests for the divisibility by a and b, …

WebStep1: We first need to iterate through each number up to the given number. Step2: We check if the given number is a prime or not. If it is a prime number, we can easily find the addition of the numbers and store it in a temporary variable. Step3: We can get the sum of all primes by printing the temporary variable.
