Number properties calculator

What properties are analyzed?

This calculator shows: even/odd, prime/composite, total divisors, digit sum, digital root, whether it's a perfect square/cube, whether it's perfect/abundant/deficient, and its prime factorization.

Example: 42

42 is even, composite, has 8 divisors (1,2,3,6,7,14,21,42), digit sum = 6, prime factorization = 2 × 3 × 7, deficient (proper divisor sum = 54).
