# Project Euler #12: Highly divisible triangular number

_{This problem is a programming version of Problem 12 from projecteuler.net}

The sequence of triangle numbers is generated by adding the natural numbers. So the 'th triangle number would be . The first ten terms would be:

Let us list the factors of the first seven triangle numbers:

We can see that is the first triangle number to have over five divisors.

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