WebbSimple methods. The simplest primality test is trial division: given an input number, n, check whether it is evenly divisible by any prime number between 2 and √ n (i.e. that the division leaves no remainder).If so, then n is composite.Otherwise, it is prime. For example, consider the number 100, which is evenly divisible by these numbers: WebbStep 1: Let’s take our prime number (p) = 11, and co-prime number (a) is 2, 3. Step 2: Using Fermat’s theorem formula of a^ {p-1}\%p = 1 ap−1%p = 1, where p p is the prime number and a a is the coprime number. Let’s directly use it in the formula. In the case of using a = 2 a = 2, p=11 p = 11, we get 210\ \%\ 11 210 % 11, which equals 1 1 .
