怎么引用穷举法，赋值

public class AA {

    public int f(int a,int b){
        int minn = Math.min(a,b);
        int m = 0;
        for(int i = minn; i >= 1; i--){
            if(a%i == 0 && b%i == 0){
                1
                break;
            }
        }
        return m;
    }
}

1这里是用穷举法的方法来写的，该怎么引用穷举法？

public class main {
public static void main(String[] args) {
AA aa = new AA();
System.out.println("最大公约数为" + aa.f(34,26));
aa = new BB();
System.out.println("最小公倍数为" + /代码三/);
}
}
