How many of the first 1200 natural numbers are either prime to 6 or to 15?
That's interesting. How do you determine if a number is prime to another number?
A number N is said to be prime to another number M if they have no common factors other than 1. Therefore, we only need to check if the greatest common divisor (GCD) of N and M is 1. If GCD(N,M) = 1, then N is prime to M.
