The LCM of two numbers is 4800 and their HCF is 160. If one of the number is 480, then the second number is

1. 16
2. 16000
3. 160
4. 1600

Answer 1

Correct Answer - Option 4 : 1600

Given:

LCM is 4,800, HCF is 160.

If one number is 480

Formula Used:

First number × Second number = LCM × HCF

Calculation:

Using the formula,

⇒ 480 × Second number = 4800 × 160

⇒ Second number = 1,600

∴ The second number is 1,600.
