WebJun 11, 2012 · Algorithm: This uses a basic recursive algorithm for finding primes. Given a list of all primes between 1 and A, A+1 is prime if it not divisible by any of the numbers in the list of primes. Start at A = 2 and add primes to the list as they are found. After N recursions, the list will contain all the primes up to N. WebWe can see that the above numbers have only two factors, 1 and the number itself. Since there are no other possible factors for these numbers, therefore, these are prime numbers. Observe the chart given below that …
