Answer 2

Answer:

here is ur answer..The property of being prime is called primality. A simple but slow method of checking the primality of a given number {} n, called trial division, tests whether n is a multiple of any integer between 2 and {\sqrt {n}}} {\sqrt {n}}. Faster algorithms include the Miller–Rabin primality test, which is fast but has a small chance of error, and the AKS primality test, which always produces the correct answer in polynomial time but is too slow to be practical. Particularly fast methods are available for numbers of special forms, such as Mersenne numbers. As of December 2018 the largest known prime number has 24,862,048 decimal digits.
