					 What is the greatest number that will divide 307 and 330 leaving remainders 3 and 7 respectively ?
- 
                        - 19
- 16
- 17
- 23
 
Correct Option: A
As we know that the largest number which when divide the numbers a, b and c give remainders as p, q, r respectively is given by H.C.F. of (a – p), (b – q) and (c – r). 
The number will be HCF of 307 – 3 = 304 and 330 – 7 = 323.
∴ Required number = 19
