(i) 867 and 255
fonmba​

Answer 1

Answer:

HCF867 and 225 by Euclid division algorithm.

867 is grater than 225

867 = 225 × 3 + 192

225 = 192 × 1 + 33

192 = 33 × 5 + 27

33 = 27 × 1 + 6

27 = 6 × 4 + 3

6 = 3 × 2 + 0

The HCF of (867 and 225) is 3.

Answer 2

$867 = 255 \times 3 + 102 \\ 255 = 102 \times 2 + 51 \\ 102 = 51 \times 2 + 0$

HENCE THE REMAINDER IS 0

THE HCF WILL BE 51
