Given that the HCF and LCM of two numbers are 225 and 360 respectively. When the first number is divided by 3, the quotient is 20. Using remainder theorem ⇒ First number = (20)(3) + r, since r = 0. So, the first number is 60. Now we know that the Product of two numbers = LCM × HCF Hence other numbers = (225×360)/60 =225×6=1350
