It works by writing down as many numbers as needed and then, traversing from lowest to highest, cross out all multiples of a number, beginning with 2. The numbers that remain are considered prime and the lowest of it will …

WebSieve of Atkin is an algorithm used to find all prime numbers upto a given number (say N) and does so in O(N) time complexity. With a modified version with enumerating lattice points variation, the time complexity … WebI recommend a sieve, either the Sieve of Eratosthenes or the Sieve of Atkin. The sieve or Eratosthenes is probably the most intuitive method of finding a list of primes. Basically you: Write down a list of numbers from 2 to whatever limit you want, let's say 1000.
