About
Analyze integers to verify primality and display factorization hints when composite.
What is a prime number
A prime number has exactly two positive divisors: 1 and itself. Composite numbers have additional divisors.
How this checker works
The utility tests divisibility up to the square root of the number and reports the smallest divisor when the number is not prime.
Common usage
Useful for algorithm practice, education, puzzle solving, and quick verification while working with hash tables or number theory examples.
