WebThe 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. Take the first number that isn't crossed off (for the first iteration this is 2) and cross off all multiples of that number from the list.
