What is the formula of finding prime numbers from 500-0?

There is no formula that will generate all the prime numbers less than or equal to 500. Perhaps the "next best thing" is that there are some formulas that will generate prime numbers for certain values that are plugged in to the formula, but not necessarily all the prime numbers. For example, the formula n2 - n + 41 will generate prime numbers for all values of n from 0 to 40, but not for all values greater than or equal to 41. But even for values of n that are less than or equal to 40, while the formula will result in a prime number, it doesn't generate all the prime numbers. The first few prime numbers generated by this formula (for n = 0, 1, 2, 3, 4, and 5) are 41, 41, 43, 47, 53, and 61. But many prime numbers get "skipped over" by using this, or any other, formula.

With a given big integer number which is the product of two prime numbers how do you find them?

First write a program to generate the prime number. After one prime number was generated, divide the big int number by the prime number. If the remainder is zero then quotient is the second prime number ( also it is important to check whether the quotient is prime number or not because sometimes you will get wrong answer). Repeat the process until you get the result.


How are these extremely large prime numbers found?

There is no formula that will specifically give you a prime number and no non-prime number. Therefore, several large numbers are tested to see if they are primes, until a prime number is found.


Does the CIA buy prime numbers?

I see no reason why they would do that. Prime numbers can be used for encryption, but there are algorithms that can quickly generate a more or less random prime number. No need to pay for the "discovery" of a specific number!


What are prime?

A prime number is a number that cannot be generated by multiplying any 2 whole numbers (aside from 1 and itself). For example, 8 is not a prime number because you can get it by multiplying 4X2. 7 on the other hand IS a prime number because there are no whole numbers you can multiply to generate it aside from 1X7.


Is there an easy formula for finding a prime number?

Yes, you can easily divide the number up to that number. If it gets divided by someone other than itself and 1, it is not prime.
