The H.C.F of two numbers is $23$ and the other two factors of their L.C.M are $13$ and $14$. The larger of the two numbers is:

Let N be the greatest number that will divide $1305$, $4665$, and $6905$, leaving the same remainder in each case. Then the sum of the digits in N is:

The greatest number of four digits which is divisible by $15, 25, 40$ and $75$ is:

The product of two numbers is $4107$. If the H.C.F of these numbers is $37$, then the greatest number is:

The C.C.D of $1.08, 0.36,$ and $0.9$ is:

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

The product of the two numbers is $2028$ and their H.C.F is $13$. The number of such pairs are:

The least multiple of $7$ which leaves a remainder of $4$ when divided by $6, 9, 15$ and $18$ is:
