The product of the LCM and HCF of two numbers is 24. The difference of the two numbers is 2. Find the numbers: |
6, 4 8, 2 7, 3 5, 5 |
6, 4 |
Let the numbers be p and (p + 2). ∴ Product of numbers = HCF × LCM ⇒ p (p + 2) = 24 ⇒ p2 + 2p – 24 = 0 ⇒ p2 + 6p – 4p – 24 = 0 ⇒ p (p + 6) – 4 (p + 6) = 0 ⇒ (p – 4) (p + 6) = 0 ⇒ p = 4 or p = – 6 Numbers = p = 4 and p + 2 = 4 + 2 = 6. ∴ Numbers are 4 and 6. |
