Number Theory

Number Theory is a focused integer toolkit for students and anyone working with divisibility, factorization, and modular arithmetic.

Features

• Single-number analysis: primality, factors, divisibility, quotient, remainder, and divisor lists for integers with |n| ≤ 10¹²
• Multi-number tools: GCD with Euclidean steps, LCM, and coprimality
• Modular arithmetic: a mod n, (a±b) mod n, and (a·b) mod n
• Prime factorization with clear breakdown and exponent form
• Divisors, quick facts, copy, share, and favorites
• Recent history
• Clean Material 3 interface with dark theme support

Built for clear structure, fast calculations, and reliable math results.
