Answer:
Step-by-step explanation:
468 = 2 x 2 x 3 x 3 x 13
222 = 2 x 3 x 37
HCF = 2 x 3 = 6
6 = 222 - 216
= 222 - (24) 9
= 222 - (468–444)9
= 222 - (468)9 + (444)9
= 222 - (468)9 + (222)(2)(9)
= 222 (19) - 468 (9)
= 468(-9) + 222(19)
6 = 468 x + 222 y …………(1)
The above is one way of expressing the HCF 6 of 468 and 222 where x = - 9 and y = 19
Now 6 = 468 (-9) + 222 (19) can be written as 468 (-9) + 222(19) + 468(222)-222(468)
= 468(213) + 222(-449)
= 468 X + 222 Y………(2)
Thus the HCF 6 has been expressed as
468 (-9) +222(19) as also 468(213)+222(-449) in two different ways.
