 1750 - 48 = 1702, so the number which we need divides 1702 completely. 
2000 - 2 = 1998, so the number which we need divides 1998 completely. 

Thus, we need to find the greatest common factor of 1702 and 1998. 
If you were to use a calculator, you will realise that number is 74, since 1702/1998 = 23/27, and 1702 = 23 * 74. 

If you are not allowed to use this method, you will need to use euclidean algorithm: 
1998 = 1702(1) + 296 
1702 = 296(5) + 222 
296 = 222(1) + 74 
222 = 74(3) + 0 

Since the last non-zero remainder is 74, the GCD of both numbers is 74, which in turn mean the number which we need is 74.
