java class wrapper

I wrote the class that computes GCD.

public class GCD {
 public static int calcGCD( int[] array ) { /* ... */ } }

Is it possible tu use it as agregate function in sql. How to write a wrapper to it?
The problem is in datatypes. I wrote something like:

(n0 number, n1 number, n2 number) return number as
language java name 'GCD_LCM.calcGCD(int[]) return int'; or
(n0 myNumberList) return number as

language java name 'GCD_LCM.calcGCD(int[]) return int';

where myNumberList is table type.
It doesn't work.
Do you know any other method to compute GCD i sql or pl/sql?
