1) Use the Euclidean Algorithm to nd the greatest common divisor of 71407 and 2020. (Write down all of the steps, so that you ar

Olenka [21]

Answer:

Step-by-step explanation:

We have

$71407 = 2000(35)+1407\\2000 = 1407+1(593)\\1407= 2(593) + 221\\593 = 2(221) = 151\\221=151+70\\151=2(70)+11\\70 = 6(11)+4\\11=2(4)+3\\4 = 3+1\\3 = 3(1)+0\\$

So we find GCD = 1

2) By back substitution we get

71407 (543) - 19387(2000) =1

So x = 543 and y = -19387

Because we got 71407 (543) - 19387(2000) =1

y cannot be positive

y can only be negative
