The product of two co-prime numbers is 540. Then their LCM is =?

Question: The product of two co-prime numbers is 540. Then their LCM is =?Solution: If HCF of two or more numbers is 1, then two or more numbers are co-prime numbers. HCF of co-prime number is always 1 ∴ Product of number = LCM × HCF⇒ LCM × 1 = 540⇒ LCM = 540
