The LCM of two numbers is 126 times their HCF. If their HCF is 7 and the difference between the two numbers is five times the HCF, then the product of the two numbers is:
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 6174.
Product of numbers = HCF × LCM
HCF = 7
⇒ LCM = 126 × HCF = 126 × 7 = 882
⇒ Product = HCF × LCM = 7 × 882
⇒ Product = 6174
