If d is the hcf of 56, 72 find x and y satisfying d=56x+72y

x = 4, y = - 3

Step-by-step explanation:

Using the Euclidean Algorithm

72 = 1 × 56 + 16 → (1)

56 = 3 × 16 + 8 → (2)

16 = 8 × 2 + 0 ← finish when remainder is 0

Hence gcd of 56 and 72 is 8

From (2)

8 = 1 × 56 - 3 × 16 → use (1) to replace 16

8 = 1 × 56 - 3(72 - 1 × 56 )

  = 1 × 56 - 3 × 72 + 3 × 56

  = 4 × 56 - 3 × 72

[ which is in the form 56x + 72y ]

with x = 4 and y = - 3
