Question

What is the product of the smallest prime number that is greater than 50 and the greatest prime number that is less than 50?
A. 2400
B. 2491
C. 2450
D. 2241

Answer 1

Hint: In order to solve this question we will use the definition of prime number as it is a number that is only divisible by itself or by 1. So by using it we will try to find out the prime number.

Complete step-by-step answer:
We know that a prime number is a number that is only divisible by itself.
The greatest prime number that is less than 50 is 47 and the smallest prime number that is greater than 50 is 53 because both 47 and 53 are divisible by only itself.
Therefore the product will be:
$47 \times 53 = 2491$
Hence, the product of the greatest prime number that is less than 50 and the smallest prime number that is greater than 50 is 2491.

Note: The given problem is simple and based on the definition of prime number. To solve this problem we have to only satisfy the conditions given in the question keeping in mind the definition of the prime number. Similar questions can be formulated on whole numbers, integers, odd numbers, even numbers etc. So remember the definitions of all these numbers.
