# Find the L C M ?

The ratio of two numbers is 3: 4 and their H C F is 4. Their L C M is :

- 44
- 48
- 52
- 60

**Answer: (2) 48**

**Explanation:-
**The ratio of two numbers = 3: 4

Let the two number be 3X and 4X.

Then, the H C F of 3 X and 4 X = 4

X = 4

Therefore, the two numbers = 3 x 4 = 12 and 4 x 4 = 16

The factors of 12 = 2 x 2 x 3

the factors of 16 = 2 x 2 x 2 x 2

Then, the L C M of 12 and 16 = 2 x 2 x 2 x 2 x 3

= 48

Hence, the answer is (2) 48.
