Unusual way to achieve π: Generating Pi from random numbers

The purpose of this repo is to gather (programming) solutions for the peculiar procedure for generating / achieving π (Pi) that Matt Parker presented in this video.

Why

1. In commemoration for Pi Day 2017.
2. Having fun.
3. No apparent logic reason.

How does it work

Since the Probability of Two (random) Integers Being Coprime is given by:

Proof and demonstration

We can generate lots of numbers and calculate π by:

All solutions are from these users (in no particular order), some are quite efficient others not so much. Regardless thanks very much.
