Greatest Common Divisor of Set of Integers/Examples

Examples of Greatest Common Divisors of Sets of Integers

Example: $39$, $42$, $54$

Let $S = \set {39, 42, 54}$.

The greatest common divisor of $S$ is:

$\map \gcd S = 3$

Example: $49$, $210$, $350$

Let $S = \set {49, 210, 350}$.

The greatest common divisor of $S$ is:

$\map \gcd S = 7$
