WebOct 27, 2014 · 1 Answer. There is a theorem that states if you have the canonical representation of an integer being a 1b1 * a 2b2 ... a nbn then the number of divisors of this integer is (b 1 + 1) * (b 2 + 1) ... (b n + 1). Now that you have this theorem, you can modify slightly Eratosthenes's sieve to get all integers up to 100 000 in canonical form. WebJan 20, 2024 · To find the number of divisors you must first express the number in its prime factors.
