## Description

Number Theory is a focused integer toolkit for students and anyone working with divisibility, factorization, and modular arithmetic.<br><br>Features<br><br>• Single-number analysis: primality, factors, divisibility, quotient, remainder, and divisor lists for integers with |n| ≤ 10¹²<br>• Multi-number tools: GCD with Euclidean steps, LCM, and coprimality<br>• Modular arithmetic: a mod n, (a±b) mod n, and (a·b) mod n<br>• Prime factorization with clear breakdown and exponent form<br>• Divisors, quick facts, copy, share, and favorites<br>• Recent history<br>• Clean Material 3 interface with dark theme support<br><br>Built for clear structure, fast calculations, and reliable math results.
