The HCF of two numbers is 15 and their LCM is 225. If one of the number is 75, then the other number is :

1. 105
2. 90
3. 60
4. 45

Correct Option: D

Given , LCM = 225 , HCF = 15 , First number = 75 , Second number = ?
As We know that ,
First number × Second number = HCF × LCM
⇒ 75 × Second number = 15 × 225

∴ Second number =	15 × 225	= 45
	75
