Quick Prime Testing
- Open the Prime Checker tool on the HeronTool website.
- Enter a positive integer, e.g., "97".
- Click "Test" – the tool instantly shows: 97 is prime. For a composite like "100", it will say "not prime" and display its factors.
Generating Prime Lists
- Use the "range generation" feature in Prime Checker (if available), input start and end values, e.g., 1 to 100.
- The tool lists all primes in that range, highlighted for clarity.
- For larger ranges, adjust inputs, but note that big numbers may take slightly longer.
Prime Factorization
- For composite numbers, use the Prime Factor tool.
- Enter a composite number, e.g., "84".
- Click "Factor" – the tool returns the product: 2 × 2 × 3 × 7.
- This tool also handles large numbers, useful for math research or basic cryptography.
FAQ
Q: Does the prime checker support negative numbers?
A: No, primes are defined as natural numbers greater than 1, so please enter positive integers only.
Q: What do exponents in the factorization result mean?
A: For example, 2^2 means 2×2. The tool displays as a product to avoid confusion.
Q: Can the tools handle very large numbers?
A: Yes, but for numbers with more than ~20 digits, response time increases – please be patient.
