Answer: (4) 48
Explanation:-

Let be the two numbers are 3X and 4X
Then, X = 4         (Given in the question HCF  = 4)
Therefore , numbers are 3 x 4 = 12 and 4 x 4 = 16
The LCM of 12 and 16
12 = 2 x 2 x 3
16 = 2 x 2 x 2 x 2
The LCM of 12 and 16 = 2 x 2 x 2 x 2 x 3
= 48

Hence, the answer is (4) 48.
