Question : The HCF and LCM of the two numbers are 20 and 2880, respectively. If one of them is 180, then find the other number.
Option 1: 660
Option 2: 350
Option 3: 300
Option 4: 320
Correct Answer: 320
Solution :
Given number = 180
HCF = 20 and LCM = 2880
We know the multiplication of two numbers = LCM × HCF
⇒ 180 × Second number = 20 × 2880
Hence, the correct answer is 320.
