If the HCF of two numbers is 12 and their LCM is 360, and one number is 60, what is the other number?

Q: If the HCF of two numbers is 12 and their LCM is 360, and one number is 60, what is the other number?

The correct answer is A. Use the fundamental relationship: HCF × LCM = Product of two numbers. So 12 × 360 = 60 × other number, which gives other number = 4320 ÷ 60 = 72. Remember the trick: HCF × LCM = First × Second.
