Given that the HCF and LCM of two numbers are 225 and 306 respectively. When the first number is divided by 3, the quotient is 15 Using remainder theorem ⇒ First number = (15)(3) + r, since r = 0. So, the first number is 45. Now we know that the Product of two numbers = LCM × HCF Hence other numbers = (225×306)/45 =306×5=1530
