Correct option is D
Given:
The product of two prime numbers is 437.
Solution:
Let the two prime numbers be a and b.
a × b = 437
Check prime numbers starting from 2 up to the square root of 437.
437 is not divisible by 2, 3, 5, 7, 11, 13, or 17.
Check divisibility by 19.
= 23
Both 19 and 23 are prime numbers.
The two numbers are 19 and 23.
The smaller prime number is 19.
Final Answer
So the correct answer is (d)
