What is the greatest number that will divide 43, 91 and 183 so as to leave the same remainder in each case?
How did you get that answer?
The solution is based on finding the greatest common divisor (GCD) of the three numbers after taking their difference in pairs. By doing this, we get the remainders: 
(91-43) = 48 
(183-91) = 92 
(183-43) = 140 
We then calculate the GCD of the remainders, which is 4. Therefore, 4 is the greatest number that will divide 43, 91 and 183 so as to leave the same remainder in each case.
