  1. The HCF (GCD) of a, b is 12, a, b are positive integers and a > b > 12. The smallest values of (a, b) are respectively
    1. 12, 24
    2. 24, 12
    3. 24, 36
    4. 36, 24
Correct Option: D

HCF of a and b = 12
∴ Numbers = 12p and 12q , where p and q are prime to each other.
∴ a > b > 12
∴ a = 36 ; b = 24
