Fermat's Little Theorem examples

Find the least residue (modulo p) using Fermat's Little Theorem; or find the remainder when dividing by p. We start with a simple example, so that we can easily check the answer, then look at much bigger numbers where the answers cannot be directly checked on a calculator.

You are a fantastic teacher! Thanks so much.

This was honestly so helpful. I could not for the life of me understand how modulo notation worked, and seeing this explained with the theorem got me unstuck in the middle of a project. Thank you so much!

Sometimes it’s better to see an application first, and only thereafter lean into the theory. Thanks, Jay, for starting me on the path towards understanding this beautiful theorem. Your examples were incredibly poignant 🏆🙌🏽🎊

[saolaobri]

This was extremely helpful having three levels of examples!

[altairezio]

Thank you very much for such a clear and an elegant explanation!

[kunalsinghgusain]

Loved it. Now I know the application of this theorem.

[Robin-onvo]

Thank you very much, helped me a lot for my first year of computer science study in france !
Best video on the subject on the 4 i watched
