Yes but at step 2 the task is reduced to a smaller pair of numbers, to which the extended Euclidean algorithm can be applied. This is an immediate saving in processor time. Step 2 = Find r -1 mod a...

Calculating inverses quickly.

Do you think this would be faster than the extended Euclidean Algorithm for finding inverses?

For a given a find a-1 (mod m)

1. Let m = r mod a
2. Find r -1 mod a
3. Let x = a - r -1 (ie, x =...
