Created: April-09, 2021 | Updated: November-26, 2021 In the world of mathematics, the shortest distance between two points in any dimension is termed the Euclidean distance. It is the square root of the sum of squares of the difference
between two points. I'm trying to write the Euclidean Algorithm in Python. It's to find the GCD of two really large numbers. The formula is a = bq + r where a and b are your two numbers, q is the number of times b divides a evenly, and r is the remainder. I can write the code to find that, however if it the original numbers don't produce a remainder (r) of zero then the algorithm goes to step 2 => b = rx + y. (same as the first step but simply subbing b for a, and r for b) the two steps repeat until r divides both a and b evenly. This is my code, I haven't yet figured out how to do the subbing of values and create a loop until the GCD is found.

Taken from Algorithms 4th edition. Note: if your numbers are REALLY REALLY large then try to increase the recursion limit by:
but be very very careful with it. I was able to fill my 12GB RAM and cause a freeze quite easily. answered May 15, 2021 at 22:27 I think that's the shortest solution:
answered Sep 29, 2021 at 18:44 I think there's one missing important condition for Euclidean Algorithm to work, which is a >= b > 0. So may I suggest this code I just made (quite long cuz I haven't viewed prev answers before building it haha.
