Comparing numbers using very basic if statement c#

I want the user to enter 3 separate integers and for the program to spit back which numbers are equal to each other of if they are not equal to each other. For my code here, I can get it to say they all equal to each other, and the first two are equal, but not for the first and third. I am assuming it's because my else statement isn't placed in the braces correctly.

 using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using static System.Console;

namespace Compare3Numbers
{
    class Program
    {
        static void Main(string[] args)
        {

            const int ONE = 1;
            const int TWO = 2;
            const int THREE = 3;

            int number1;
            int number2;
            int number3;

            Write("Enter the first number: ");
            number1 = int.Parse(ReadLine());

            Write("Enter the second number: ");
            number2 = int.Parse(ReadLine());

            Write("Enter the third number: ");
            number3 = int.Parse(ReadLine());

            if (number1 == number2)
            {
                if (number2 == number3)
                {
                    WriteLine("All your numbers are equal!");
                }
                else
                {
                    if (number1 == number2)
                    {
                        WriteLine("Your first two numbers are equal!");
                    }
                    else
                    {
                        if (number1 == number3)
                        {
                            WriteLine("Your first number and third number are equal!");
                        }
                    }
                }
            }






            //debug line
            WriteLine("Press any key to continue...");
            ReadLine();
        }
    }
}
