This article will explore the concept, offer an in-depth explanation of a calculator designed to compute Bézout’s identity, and discuss its various applications.
Definition
Bézout coefficients are named after the French mathematician Étienne Bézout. They represent a linear combination of two integers that equates to their greatest common divisor (GCD). This mathematical concept is expressed through Bézout’s identity, a theorem with profound implications in algebra and beyond.
Detailed Explanations of the Calculator’s Working
The calculator uses the Extended Euclidean Algorithm to compute the Bézout coefficients. By accepting two integers, the calculator finds the coefficients that satisfy Bézout’s identity. It iteratively applies divisions and modulo operations to find the GCD and corresponding coefficients. The result offers valuable insights into the relationship between the given integers.
Formula with Variables Description
Bézout’s Identity is mathematically expressed as: For any integers 𝑎 and 𝑏, there exist integers 𝑥 and 𝑦 such that:
𝑎𝑥 + 𝑏𝑦 = gcd(𝑎, 𝑏)
Example
Consider the integers 252 and 105. Using the calculator, one finds the Bézout coefficients x = 3 and y = -7, satisfying the equation: 252 * 3 + 105 * (-7) = 21 Thus, the GCD of 252 and 105 is 21.
