World says Prime numbers does not have any pattern! We say that Prime numbers are very disciplined, they fly like birds fly with particular pattern! They are difficult to understand but if you work with them for long time, they start to cooperate :). Prime numbers are atomic numbers, they are like diamonds scattered in numbers system! Facts .. * We have developed fastest algorithm to find Primes up to n. We don’t cache any data, every time Primes are calculated fresh from oven! * We can find Prime numbers up to n without division/multiplication once in a loop. That’s known as organic Prime numbers *We are displaying important information like , Primes, Prime Counts, Percentage , highest/lowest no of primes per 100 , Highest gap in 2 primes! Ending with 1,3,7,9 details. * Twin and Quads Primes, time taken to find Primes up to n. * Collatz Conjecture is very interesting , how every number somehow comes down to 1 , you can verify and study that. * We think that it's a great way to study Prime numbers! *You can find N'th Prime number approximately! Indians have contributed a lot in math world! I have come up with Prime count formula better than all previous formulas. I will let you be the judge of that. If this formula is approved by Math department, we can see Ladhe'sPrime - LP(n) function in all the programming languages and scientific calculators so that next generation of inventions are possible! This invention is as big as inventing zero. This invention will change mankind's ability and I wanted to see how we can give this capability to the developer community.  This could be possible solution to millennium-problems , Riemann-hypothesis! https://www.claymath.org/millennium-problems/riemann-hypothesis ## Key features - Fastest algorithm for finding primes up to n - Organic prime number calculation without division/multiplication - Display of prime counts, percentages, and prime gaps - Information on twin and quad primes - Collatz Conjecture verification - Approximate N'th prime number calculation ## Frequently asked questions about Ladhe's Primes ### What is Ladhe's Primes? Ladhe's Primes is an educational application designed to help users explore and understand the patterns and properties of prime numbers.
