Prime number. In a natural number greater than 1, except for 1 and the integer itself, it cannot be divisible by other natural numbers. Prime numbers play an important role in number theory. A number larger than 1 but not a

To determine the prime number, you can open the given number and use this value to divide the number from 1 to open the house or only the largest integer smaller than the given one. If the number cannot be divisible, this is a
