Let N be the greatest number that will divide 90, 112, 134 leaving the same remainder in each case. Then sum of the digits in N is:

How many pairs of natural numbers (x, y) exist such that x>y and the product of x, y and HCF (x, y) = 2520? solve this 

The LCM and the HCF of the numbers 25 and 50 are in the ratio:

Find the HCF of 244 and 118.

Find the least number of equal sizes square tiles which can be fitted in a rectangular room whose sides are 360 m and 480 m?

The product of two positive integers is 2646. If their HCF is 7 and their sum is 105, then find the difference between the numbers.

The product of two numbers is 3600 and their GCD is 30. What is the LCM?

The LCM of two numbers is 33 times of their HCF. The sum of the LCM and HCF is 850. If one number is 25, then the other number is:

Three numbers are in the ratio 2:5:7 respectively. If the HCF of the numbers is 6, then find the LCM of the numbers.
