If the LCM of two numbers is 72 and their product is 1728, then what is the HCF of the numbers?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 24.
LCM of two numbers = 72
The product of the numbers = 1728
We know that
LCM × HCF = 1st number × 2nd number
⇒ 72 × HCF = 1728
HCF = 1728/72 = 24
