37.3.2 Primes and the Fundamental Theorem of Arithmetic

Core idea

Primes are the building blocks that can't be broken down further, and every integer splits uniquely into a product of primes, like 12 = 2²·3.

Module goal. Starting from divisibility and remainders among the integers, meet the prime numbers as building blocks and congruence as a clock arithmetic, and feel the beauty of pure structure.
