The HCF and LCM of two numbers are 12 and 180 respectively. If one of the numbers is 36, what is the other number?
- (A)72
- (B)48
- (C)5
- (D)60
Correct answer: (D) 60
For any two numbers, product of the numbers = HCF × LCM. So the other number = (12 × 180) ÷ 36 = 2160 ÷ 36 = 60.
Shortcut: Other number = HCF × LCM ÷ given number.
