Two numbers are in the ratio 2:8. The product of their H.C.F. and L.C.M. is 3600. The sum of the numbers is:
The HCF of 2165 and 7409 is 239, their LCM is:
The H.C.F. of two numbers is 22 and the other two factors of their L.C.M. are 9 and 11. The larger of the two numbers is:
If the sum of 2 numbers is 185, their LCM is 1700 and HCF is 5. Then the difference between 2 numbers is:
The LCM of two numbers is 432 and their HCF is 55. If one of the numbers is 132, the other number is:
Two numbers are in the ratio 3:5 and their HCF is 20. Their LCM is
