Question

Is the number 1,997 prime? ​
A) Prime
B) Not prime

Quizplus · Accepted Answer

One way to check if a number is prime is to divide it by every integer from 2 to its square root (rounded up) and see if any of them divide evenly. For 1,997, this means we would check all integers from 2 to the square root of 1,997, which is approximately 44.7 (rounded up to 45). None of these integers divide evenly into 1,997, so it is indeed prime. Therefore, the best choice is A, prime.
