{
    class Program
    {
        static void Main(string[] args)
        {

            var intCollection = new List<System.Numerics.BigInteger>() { 234, 213, 666, 879 };
            var product = intCollection.Aggregate((a, b) => a * b);
            Console.WriteLine("Product is {0}", product);
            Console.ReadKey();
        } 
    }
}

Result
