The HCF and LCM of two numbers are 11 and 231 respectively. If one of the numbers is 33, what is the other number?
- (A)88
- (B)66
- (C)7
- (D)77
Correct answer: (D) 77
For any two numbers, product of the numbers = HCF × LCM. So the other number = (11 × 231) ÷ 33 = 2541 ÷ 33 = 77.
Shortcut: Other number = HCF × LCM ÷ given number.
