# Problem 12 Highly divisible triangular number

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:

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?
