Detailed Solution

Concept-Write both 96 and 404 as the product of prime factors. Now for HCF, let's look at the common factors that exist in the product of both  numbers. Evaluate the product and get HCF. To find the LCM, write the product of the prime factors without repeating the general ones. To get the LCM now, please rate the product.
 Question ImageThus, the HCF (96, 404) is 2 × 2 = 4.
As you know, the product of  two integers is equal to the product of  HCF and LCM.
HCF × LCM = Product of the two numbers
Question ImageHence, the correct option is 1.
