It hassomething like one billion numerals in the number. The prime numbers between 30 and 55 are 31, 37, 41, 43, 47, and It is also quite slow due to the multiple nested enumeration operations.
The numbers 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89 and 97 are prime.
Prime numbers between ? The two prime numbers between 20 and 30 are 23 and What are the prime numbers between 0 and 20? If he had tried a smaller range such as one million, he still would have found it takes in the range of seconds as implemented.
That is why only a page segmented approach such as that of PrimeSieve can handle this sort of problem for the range as specified at all, and even that requires a very long time, as in weeks to years unless one has access to a super computer with hundreds of thousands of cores.
What are all of the prime numbers between 30 and 55? What prime numbers are between 1 and 20? Prime numbers between 1 and 20? The answer is 2,3,5,7,11,13,17, Either of the two static methods can be called and tested with the using statements and with the static Main method as follows: However, it is still slow and memory intensive due to the List generation and the multiple enumerations as well as the multiple divide implied by the modulo operations.
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.
WriteLine "This program generates prime sequences. The above code works because it limits the computation to only the odd numbers and only does modulo divisions up to the square root of the current number being tested.
Scientists announced they found the highest Prime Number.
What are the prime numbers between 1 and 20? The prime numbers between 1 and 25 are: The correct answer is 2, 3, 5, 7, 11, 13, 17, and This takes an hour or so to display the primes up to a billion, so one can imagine the amount of time it would take to show all the primes to ten thousand trillion 10 raised to the sixteenth powerespecially as the calculation gets slower with increasing range.
What are the prime numbers between 20 and ? Prime numbers are numbers that can only be divided by one and itself. The prime numbers between 0 and 20 are: What are the prime numbers between 15 and 30? What are the prime numbers between 30 ?
