Calculate the GCD(2095,200) using Euclidian algorithm:
Steps of Euclidian algorithm:
Finding the of GCD(X, Y):
Step 1: If X = 0 then GCD(X, Y) = Y
Step 2: If Y = 0 then GCD(X, Y) = X
Step 3: Write X as X = Y * Q + R quotient remainder form.
Step 4: Find the GCD(Y,R) repeating the above steps as GCD(X, Y) = GCD(Y,R)
Calculating GCD(2095,200) using Euclidian algorithm:
2095 = 200 * 10 + 95 (2095 ÷ 200 = 10 Quotient with Reminder R = 95)
200 = 95 * 2 + 10 (200 ÷ 95 = 2 Quotient with Reminder R = 10)
95 = 10 * 9 + 5 (95 ÷ 10 = 9 Quotient with Reminder R = 5)
10 = 5 * 2 + 0 (10 ÷ 5 = 2 Quotient with Reminder R = 0)
• When remainder R = 0 then the GCD is the divisor, Y, in the equation form X = Y * Q + R
• Here, in the above last equation. When R = 0, Y = 5. So, GCD = 5
GCD(2095,200) = 5
Description:
• GCD of 2095 and 200
X ≠ 0
Y ≠ 0
2095 ÷ 200 = 10 with R = 95. (Quotient Remainder form: 2095 = 200 * 10 + 95)
Find the GCD(200, 95) as GCD(2095, 200) = GCD(200, 95)
• GCD of 200 and 95
X ≠ 0
Y ≠ 0
200÷ 95= 2 with R = 10. (Quotient Remainder form: 200 = 95 * 2 + 10)
Find the GCD(95, 10) as GCD(200, 95) = GCD(95, 10)
• GCD of 95 and 10
X ≠ 0
Y ≠ 0
95 ÷ 10= 9 with R = 5. (Quotient Remainder form: 95 = 10 * 9 + 5)
Find the GCD(10,5) as GCD(95, 10) = GCD(10,5)
• GCD of 10 and 5
X ≠ 0
Y ≠ 0
10 ÷ 5 = 2 with R = 0. (Quotient Remainder form: 10 = 5 * 2 + 0)
When R = 0 then GCD = Y. So, GCD(2095, 200) = 5.

Extended Euclidian Algorithm (page 4 of last lecture, more on algorithms) Write code that asks for and gets two integers, then computes and displays their greatest common divisor using the Extended Euclidian Algorithm (EEA). The EEA should be implemented as a function that takes two integers are arguments and prints their GCD.
