Examples of Use of Euclidean Algorithm

The GCD of $24$ and $138$ is found to be:

$\gcd \set {24, 138} = 6$


Integer Combination

$6$ can be expressed as an integer combination of $24$ and $138$:

$6 = 6 \times 24 - 1 \times 138$


Proof

\(\text {(1)}: \quad\) \(\ds 138\) \(=\) \(\ds 5 \times 24 + 18\)
\(\text {(2)}: \quad\) \(\ds 24\) \(=\) \(\ds 1 \times 18 + 6\)
\(\text {(3)}: \quad\) \(\ds 18\) \(=\) \(\ds 3 \times 6\)
