Three number are in the ratio of 3 : 4 : 5 and their L.C.M. is 2400. Their H.C.F. is:

Two numbers are in the ratio of 3 : 5. Their L.C.M. is 90. The numbers are

Two numbers are in the ratio 21 : 10. If their HCF is 11, then the sum of the numbers is

Let L be the LCM and Hbe the HCF of two given numbers. L and H are in the ratio 3 : 2. If the sum of the two numbers is 45, then what is the product of the numbers?

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
