This video is about the uses and importance of the "Fundamental Theorem of Arithmetic" (also known as the uniqueness of prime factorisation (UPF)), which finishes with a proof of the theorem.

Further reading and motivation for the proof of UPF: https://www.dpmms.cam.ac.uk/~wtg10/FT...

Chapters:
0:00 Introduction
1:30 Why is UPF not trivial?
7:20 Why is UPF "fundamental"?
14:19 Proof of UPF
21:40 Conclusions


(As pointed out by a comment), at 20:45 it should say "ka is less than 2p" rather than "kb is less than 2p" on the screen.
