20 окт. 2017 г. · I'm trying to get a fast way to determine if a number is prime using Python. I have two functions to do this. Both return either True or False.

28 сент. 2017 г. · The best efficient way to find the Prime numbers is to use the Sieve of Eratosthenes algorithm. Here is the code: n = int(input("enter the ...

16 апр. 2021 г. · To test if a number is prime, I do: def isprime(n): if n < 2: return False for i in range(2, n): if n % i == 0: return False else: return True

31 июл. 2020 г. · The best method known to me is of order sqrt(n). I read about Fermat's Primality Test and Miller-Rabin Primality Test. They operate in O(log(n)) time.

14 окт. 2020 г. · There is no fast way to do this. It is kind of the beauty of prime numbers. It takes a lot of compute time to know if a large number is prime.

12 июн. 2019 г. · I wrote this program to check weather the no. is prime or not but it shows the number is prime multiple times. how can i solve it

9 апр. 2016 г. · What would be the fastest way to check if a given large number is prime? I'm talking about numbers the size of around 10^32. I've tried the ...

12 дек. 2022 г. · You want to use a boolean True/False variable to track if the number is prime or not, and set it accordingly in your for loop.

10 июл. 2013 г. · Yes there is. For one, you could check for 2 separately and then loop through only odd numbers. That would cut the search loop in half.

7 июл. 2020 г. · I wrote an equation based prime finder using MillerRabin, it's not as fast as a next_prime finder that sieves, but it can create large primes and you get the ...
