Theory of numbers: Fundamental theorem of arithmetic
Channel: Richard E Borcherds
Date: 2021-01-25

This lecture is part of an online undergraduate course on the theory of numbers.

We use Euclid's algorithm to prove the fundamental theorem of arithmetic, that every positive number is a product of primes in an essentially unique way. 

We then use this to prove Euler's product formula for the Riemann zeta function.
