Best Answer

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.

The set is well defined. Whether or not a given integer belongs to the set of prime numbers is clearly defined even if, for extremely large numbers, it may prove impossible to determine the status of that number.

The same way as with smaller numbers, it may take longer. Just keep dividing by prime numbers until all the factors are prime.

Some think it is an interesting challenge. Prime numbers of up to a few hundred digits have real practical applications, in cryptography. However, the largest prime numbers found are much, much greater than that.Some think it is an interesting challenge.

If you're asking us to type the tens of millions of known prime numbers, the answer is no.

Large primes numbers are used in public key encryption systems as when multiplied together to create an even larger composite number it is extremely difficult to factorise this number into its component primes - this is what gives the encryption its strength. It is the knowledge of the large prime factors of the even larger composite number which allows the encryption and decryption keys to be determined; they are dependent on each other and the prime factors.
