Prime Number Checker — Factor & Factorization | ConverterPilot
Input a valid integer to run calculations
About This Tool
The interactive Prime Number Checker verifies primality, generates custom ranges using the Sieve of Eratosthenes, solves multi-number GCF/LCM values, and renders branching factor trees using SVG shapes.
How to Use
- Toggle between Primality Test, Sieve Generator, or GCF/LCM tabs.
- Enter numbers in the inputs. The tool processes calculations in real-time.
- In primality mode, see prime status, divisors list, and study the factor tree diagram.
- In sieve mode, visual grid lists highlight prime grids in blue for easy scan.
