Break an integer into prime powers, then go further: divisor count, divisor sum, Euler’s φ, radical, Möbius value, square-free status, factor tree and exact multiplication verification.
Deterministic primality for factors ≤ 2⁶⁴−1. Advanced factorization accepts up to 120 digits and clearly labels larger probable-prime factors.
