+# The sequence of triangle numbers is generated by adding the natural numbers.
+# So the 7th triangle number would be 1 + 2 + 3 + 4 + 5 + 6 + 7 = 28. The first ten terms would be:
+#
+# 1, 3, 6, 10, 15, 21, 28, 36, 45, 55, ...
+#
+# Let us list the factors of the first seven triangle numbers:
+#
+#  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?
