This is just a simple example of how we can use a Predicate<T> and an Enumarable

Enumerable & Predicate

namespace TestArea
{
    using System;
    using System.Collections.Generic;
    using System.Linq;
    class Program
    {
        static void Main(string[] args)
        {
            int upperBond = int.Parse(Console.ReadLine());

            List<int> numbers = Enumerable.Range(1, upperBond).ToList();
            int[] input = Console.ReadLine()
                .Split()
                .Select(int.Parse)
                .Distinct()
                .ToArray();
            for (int i = 0; i < input.Length; i++)
            {
                Predicate<int> divisible = num => { return num % input[i] == 0; };
                numbers = numbers.FindAll(divisible);
            }
            Console.WriteLine(string.Join(" ", numbers));

            

        }
    }
}
