Problem:
If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23. Find the sum of all the multiples of 3 or 5 below 1000.
If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23. Find the sum of all the multiples of 3 or 5 below 1000.
My Solution:
Note: You can simplifies the coding :)
- static void Main(string[] args)
- {
- int sumOfMultiples = 0;
- for (int i = 1; i < 1000; i++)
- {
- if (i % 3 == 0 || i % 5 == 0)
- {
- sumOfMultiples += i;
- }
- }
- Console.Write("The Sum of Multiples of 3 or 5 below 1000 is :");
- Console.Write(sumOfMultiples);
- Console.ReadLine();
- }
