Returns the greatest common divisor of an array of numbers. «a» should be an array of positive integers indexed by «I».

The greatest common divisor is the largest integer that divides evenly into all integers in «a».

	M ▶
	1	2	3
a ▻	2297295	2457	10395

GCD(a,M) → 189

GCD( [23*5, 23*7, 23*9, 23*11] ) → 23

To use this function, you must add the following library to your model.
