FIRSTLY BY EUCLIDS DIVISION LEMMA,
1288= 575*2+138 ......... (2)
575= 138*4+23 ........ (1)
138= 23*6+0
THERFORE, HCF= 23.
Now,
23=575-138*4 .............. [from (1)]
23= 575-(1288-575*2) *4 ...............[from (2)]
23= 575-1288*4+575*8
23= 575*9+1288* (-4)
therfore the hcf can be written in form of 1288* (-4) + 575*9
hence x= -4 and y=9
so they are not unique..........
