ReadKey true ; Console. The following true Sieve of Eratosthenes implementation runs about 30 times faster and takes much less memory as it only uses a one bit representation per number sieved and limits its enumeration to the final iterator sequence output, as well having the optimisations of only treating odd composites, and only culling from the squares of the base primes for base primes up to the square root of the maximum number, as follows: What are the prime numbers between 10 and 30?

The prime numbers from 1 to 20 are 2, 3, 5, 7, 11, 13, 17 and Even if this were corrected, the question code produces very slow output because it gets bound up doing bit divisions of very large quantities of composite numbers all the even numbers plus the odd composites by the whole range of numbers up to that top number of ten raised to the sixteenth power for each prime that it can possibly produce.

It can become an optimized Trial Division with less enumeration overhead as follows: The prime numbers between 30 and 40 are 31 and The numbers 2, 3, 5, 7, 11, 13, 17, 19, 23 and 29 are prime including the boundaries.
