Two numbers are in the ratio 5: 6. ∴ If one number is 5X then other one is 6X. The HCF of the above two numbers is X as 5 & 6 are relative prime numbers. So the highest common factor present between them = X Given that, their HCF is 5 ⇒ X = 5 ∴The two numbers are 5×5 = 25; 6×5 = 30; Now LCM of 25 & 30 is 150.Related questions
