While there are other ways to do this (like applying our formula recursively), the fastest way seems to be to enumerate all primes up to x2−−√3x23, which can be done with the sieve of Eratosthenes. First, we identify and store all prime numbers in [1,x−−√][1,x], and...
of prime numbers to number theory and mathematics in general stems from the fundamental theorem of arithmetic which states that every positive integer larger than 1 can be written as a product of one or more primes in a way which is unique except possibly for the order of the prime factors....
Method for Determining the Minimum number of Primes Between the Perfect Squares of Consecutive IntegersOscarson, William Randolph
If the number of distinct primes is equal to K, I increment count. The problem I'm running into is that of time. Even after implementing the sieve, it takes 10 seconds to compute the answer to 2,10000,1 (The numbers between 2 and 100000 that have 1 distinct prime factor) here's my...

Bounded gaps between primes in number fields and function fields The Hardy--Littlewood prime $k$-tuples conjecture has long been thought to becompletely unapproachable with current methods. While this sadly remains true,startling breakthroughs of Zhang, Maynard, and Tao have nevertheless madesignifica...

Pick the PrimesAfter pressing the Start button you have to click (not drag) the fruit with prime numbers written on them. There are six prime numbers on the tree. The others are composite numbers. When you have picked the six prime numbers click the Check button. The timer will then stop...
It is easy to prove that there are an infinite number of primes using Euclid's second theorem: Imagine there is a finite set consisting of all the primes. Multiply them all together, add 1, and call this N. N would not be divisible by any number in the set—there would always be a...
