Number Theory
Quadratic Residue Calculator
Determine whether an integer a is a quadratic residue modulo a prime p, and compute the Legendre symbol (a/p). Used in number theory, primality testing, and cryptographic algorithm design.
Fill in the required fields to see your result.
Number Theory
Divisibility Test Calculator
Test whether a specific number is divisible by a chosen divisor, or count all divisors up to a custom limit. Useful for simplifying fractions, factoring integers, and classroom exercises.
