Question:

What is the LCM of 3.6, 1.8 and 0.144 ?

Options:

3.6

36

3600

360

Correct Answer:

3.6

Explanation:

Number = 3.6, 1.8, and 0.144

Digit with highest digits after decimal = 0.144 

⇒ 3 digits after decimal i.e., n = 3 = 103 

⇒ 3.6 × 10 = 3600

⇒ 1.8 × 10  = 1800

⇒ 0.144 × 10 = 144

LCM of (3600, 1800, 144) = 3600

The LCM of 3.6, 1.8 and 0.144 = \(\frac{3600}{1000}\) = 3.6
