What is the sum of all prime numbers between 1 and 1000?
The ratio of the prime numbers to their log quotient should approach 1, but should never exceed it (An interesting tidbit). Actually you did the program for finding the sum of prime numbers up to 1000 and it is 76127 and the sum of first 1000 natural numbers is 3682913.
How many even prime numbers are there from 1 to 10000?

How many prime numbers are there in the range 1-10000?
Prime numbers in the range 1 to 10,000. There are 1229 prime numbers between 1 and 10,000.
What is the general formula to find the prime numbers?
Apart from 2 and 3, every prime number can be written in the form of 6n + 1 or 6n – 1, where n is a natural number. To find the prime numbers greater than 40,the general formula that can be used is n2+ n + 41, where n are natural numbers 0, 1, 2, ….., 39 Note: These both are the general formula to find the prime numbers.
How to check if a number is prime or not?
We can check if the number is prime or not in two ways. Method 1: The formula for the prime number is 6n + 1. Let us write the given number in the form of 6n + 1. 6 (3) + 1 = 18 + 1 = 19. Method 2: Check for the factors of 19. 19 has only two factors 1 and 19. Therefore, by both the method we get 19 is a prime number.
How do you find the multiples of two prime numbers?
One straightforward technique is to use the so-called Sieve of Eratosthenes. Simply start with a neatly arranged listing or printout of the numbers 1 – 1000 (or any other upper limit you desire.) Now, start a list of prime numbers with 2 and cross off 2 and all its multiples from your listing/printout.
