If x and y are co-primes, then their LCM is:

The product of 2 numbers is 1530 and their HCF is 15, then their LCM is

If x is the HCF and y is the LCM of 3/5, 6/25, 9/20, 27/50 then which one of the following is correct?

Sum of the HCF and LCM of two numbers is 504 and LCM is 55 times of HCF. If one number is 99, then the second number is

There are two numbers. HCF of both the numbers is 11, and their LCM is 693. If the first number is 77, find the second number?

The GCD of two numbers is 9 and LCM is 108. If one of the numbers is 27, then the other is
