Write a prime number that is coprime with 6. Write a composite number that is coprime with 6

Since it is coprime with 6, then it is neither a multiple of 2 nor a multiple of 3. Then the remainder of its division by 6 must be 1 or 5. All numbers conforming to this property are coprime with 6. If it is prime, then the minimum is 5; if it is composite, then the minimum is 5 ^ 2 = 25
