Use the extended Euclidean algorithm to find the greatest common divisor of 9,090 and 936 and express it as a linear combination of 9,090 and 936.
Step 1: Find ₁ and ₁ so that
9,090 = 936 9₁+₁, where 0 ≤r₁ < 936.
Then 1 = 9,090 - 936 9₁ =
Step 2: Find 92 and r₂ so that
936 = ₁.9₂ +r₂, where 0≤r₂ <1
Then

Step 3: Find 93 and r3 so that
r₁ = r₂ 93 +r3, where 0≤r3 <r₂.
Then 3

Step 4: Find 94 and r4 so that
r₂ = 73 94 +r4, where 0≤r4 <r3.
Then r4 =
Step 5: Find 95 and r so that
r3 = 74 95 +r5, where 0 <r5 <r4'
Then s

Step 6: Conclude that gcd (9090, 936) equals which of the following.
O gcd (9090, 936) = r₂-394
O gcd (9090, 936) = 4593
O gcd (9090, 936) = r₂-495
O gcd (9090, 936) = ₁₂94
O gcd (9090, 936) = 3495
Conclusion: Substitute numerical values backward through the preceding steps, simplifying the results for each step, until you have found numbers s and t so that
gcd (9090, 936) = 9,090s + 936t,
where s =
