(A) prime number is a natural number greater than $1$ that has no positive divisors other than $1$ and itself.To find the largest three-digit prime number,we check the numbers starting from the largest three-digit number,which is $999$.$1$. $999$ is divisible by $3$ $(999 = 3 	imes 333)$,so it is not prime.$2$. $998$ is an even number,so it is divisible by $2$,hence not prime.$3$. $997$ is not divisible by any prime number up to $\sqrt{997} \approx 31.57$ (i.e.,$2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31$).Since $997$ is not divisible by any of these primes,it is a prime number.Therefore,$997$ is the largest three-digit prime number.
