the common number should divide (445 - 4), (572 - 5) and (699 - 6) exactly to satisfy this situation.
i.e.the hcf of 
441, 567 and 693 is the answer to this question
441 = 7 x 7 x 3 x 3
567 = 7 x 3 x 3 x 3 x 3
693 = 7 x 3 x 3 x 11

here,we can observe that 7*3*3 is common,hence the answer is 63
2 5 2
