I believe that there is an error here:

5*740740734080 mod p = 61, not 1

However, the inverse is

5*740740734068 mod p = 1

 

I think what it is, is that the value for p in the slide is wrong.  I went from scratch to calculate all the values, and given that p, nothing comes out correctly.

p is wrong. It's not a prime. I'll replace the example with a simpler one.

Thank for pointing it out!
