The Architecture of Factors

Like Duolingo, but for The Architecture of Factors. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.

For the part of you with thirty open tabs that never became anything.

21 levels across 3 sections, about 42 minutes end to end, roughly 8 days at five minutes a day. It moves through The Anatomy of Integers, Patterns and Extremes, and Complexity and Cryptography.

Key ideas in The Architecture of Factors

  • Prime factorization is the unique 'atomic' state of an integer
  • The order of operations in a factor tree does not change the final prime composition
  • Any integer greater than 1 has exactly one prime signature
  • Each prime factor p^e contributes (e+1) choices (including p^0) to a divisor's composition
  • The total count of divisors is the product of the incremented exponents of its prime factors
  • The exponent of a prime not present in the factorization is effectively 0, contributing a multiplier of 1
  • The uniqueness and immutability of a number's prime signature regardless of the multiplication path taken.
  • Calculating the total number of divisors using the (e+1) product rule.
  • Perfect squares require all prime exponents to be even (multiples of 2)
  • The uniqueness and immutability of a number's prime signature
  • Perfect cubes require all prime exponents to be multiples of 3
  • A number is both a square and a cube if all its prime exponents are multiples of 6 (LCM of 2 and 3)
  • Calculating the total number of divisors using the (e+1) product rule
  • GCD is formed by taking the lowest power of every prime shared by both numbers
  • Identifying perfect powers by analyzing the divisibility of their prime exponents.
  • Factor lattices are organized by the number of prime factors included in each divisor
