97 is the answer.
Two is the least prime number that is lower than 203.
The largest prime number less than 50 is 47.
The lowest prime number that is less than 37 is 29.
The largest single digit composite number is 9. The largest prime number is 17 million digits long. The definition of a composite number is any number that has at least one positive divisor other than one or the number itself (it is not a prime number). The largest composite digit is therefore longer than the largest prime number by at leaf +1.
97 is the answer.
9797 is the largest prime number less than 100.
67 will be the largest prime number less than 70.
The largest prime number less than 1000 is 997.The largest prime number no less than 1000 is currently 257,885,161-1
Two is the least prime number that is lower than 203.
The largest prime number less than 50 is 47.
The lowest prime number that is less than 37 is 29.
Since 167 is a prime, any number smaller that 167 will be relatively prime. So, the largest number less than 100, that is 99, is relatively prime.
This is the same as asking "What is the largest prime number?". The answer would be infinity, but infinity isn't a number. There is no answer. Maybe you meant to ask: "What is the SMALLEST prime number greater than 200?". The answer to that is 211.

The largest number which can be stored in 8 bits is 255. The largest prime number which is less than or equal to 255 is 251.
Prime numbers can't have whole number square roots, of course, but the largest prime number under 400 is 397.
