Say we want to test whether the number N is prime or not. The first approach that comes to mind is probably to try to dive N by all numbers from 2 up to N-1. If the division is perfect in any of those cases (i.e., no remainder) then N is not prime. Else if it can’t b...

In the main() function, we are creating an objectPof classIsPrime, inputting the number by the user using thegetNumber()function, and finally calling theisprime()member function to check if the number entered is prime or not. Theisprime()function contains the logic to check if the number...

So, To check for prime number, We can simply check for a factor till N1/2 instead of N/2 using a while loop. If a factor is not present between 2 and N1/2, the number must be a prime number. Using this logic, we can modify the isPrime() function used in the above example as...
How to Find Prime Factorization? To find the prime factorization of a number means to write the number as a product of only prime factors. Using a factor pair such as 40 = 5 * 8 provides a factorization of 40, but not a prime factorization since 8 is not prime. Factors can be ...
