NettetBy reversing the steps or using the extended Euclidean algorithm, the GCD can be expressed as a linear combination of the two original numbers, that is the sum of the two numbers, each multiplied by an integer (for example, 21 = 5 × 105 + (−2) × 252). The fact that the GCD can always be expressed in this way is known as Bézout's identity.

For instance, $\gcd(55, 80) = 5$, therefore we can represent $5$ as a linear combination with the terms $55$ and $80$: $55 \cdot 3 + 80 \cdot (-2) = 5$ A more general form of that problem is discussed in the article about Linear Diophantine … phone tap software free download

The common divisors of 24 and 42 are ± 1, ± 2, ± 3, and ± 6. Among them, 6 is the largest. Therefore, gcd (24, 42) = 6. The common divisors of 12 and 32 are ± 1, ± 2 and ± 4, it follows that gcd (12, 32) …

NettetThe start of recursion backtracking is the end of the Euclidean algorithm, when a = 0 and GCD = b, so first x and y are 0 and 1, respectively. Further coefficients are computed using the formulas above. Similar calculators • The greatest common divisor of two integers • The greatest common divisor and the least common multiple of two integers NettetThe whole idea is to start with the GCD and recursively work our way backwards. This can be done by treating the numbers as variables until we end up with an expression that is a linear combination of our initial numbers. We shall do this with the example we used above. We start with our GCD. We rewrite it in terms of the previous two terms:

NettetThis is as far as I got: You can subtract the first entry of the $\operatorname {gcd}$ twice from the second to get $=7\operatorname {gcd} (a+2b,-b)$. Then add the second twice to the first to get $=7\operatorname {gcd} (a,-b)$. Multiplying by $-1$, an invertible element, doesn't matter, $=7\operatorname {gcd} (a,b)$.
