The HCF of three numbers 98, 175 and 210 will be:

The LCM of two numbers is 48. If those numbers are in the ratio 2 : 3 then what will be their sum?

A number between 1000 and 2000 which when divided by 30, 36 and 80 gives a remainder 11 in each case is:

The number between 4000 and 5000 that is divisible by each of 12, 18, 21 and 32 is 

The LCM of 1.2 and 2.7 is:

The L.C.M. of two numbers is 1820 and their H.C.F. is 26. If one number is 130 then the other number is:

The HCF and the LCM of two numbers are 5 and 120, respectively. If the sum of the two numbers is 55, then the sum of the reciprocals of these two numbers is equal to:

LCM of two numbers is 56 times their HCF, with the sum of their HCF and LCM being 1710. If one of the two numbers is 240, then what is the other number?
