99 is the largest composite number less than 100: its prime factorisation is 3 x 3 x 11
47 - 12 = 35
Testing the largest whole number less than 200, 199, we find that it is not evenly divisible by 2, 3, 5, 7, 11 or 13. Since the square root of 199 is between 14 and 15, there's no need to test any prime numbers higher than 14. Therefore, the answer is 198, since it is an even number, and all even numbers are composite numbers because they are divisible by 2. A composite number is the opposite of a prime number.
Literally every single even number less than 1000 is a composite number other than 2 which is prime.
