-Let us list the factors of the first seven triangle numbers:
+https://projecteuler.net/problem=13
+*/
 
- 1: 1
- 3: 1,3
- 6: 1,2,3,6
-10: 1,2,5,10
-15: 1,3,5,15
-21: 1,3,7,21
-28: 1,2,4,7,14,28
-We can see that 28 is the first triangle number to have over five divisors.

-What is the value of the first triangle number to have over five hundred divisors?
