Sieve of eratosthenes prime numbers

WebWe describe recurring patterns of numbers that survive each wave of the Sieve of Eratosthenes, including symmetries, uniform subdivisions, and quantifiable, predictive cycles that characterize their distribution across the number line. We generalize WebWith an Eratosthenes’ sieve, the multiples of each prime number are progressively crossed out of the list of all numbers being examined (in this case the numbers one to two hundred, 1 to 200). You will notice that by the time you come to crossing out the multiples of three , several have already been crossed out: 6, 12, 18 etc.
