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

  1. Toggle between Primality Test, Sieve Generator, or GCF/LCM tabs.
  2. Enter numbers in the inputs. The tool processes calculations in real-time.
  3. In primality mode, see prime status, divisors list, and study the factor tree diagram.
  4. In sieve mode, visual grid lists highlight prime grids in blue for easy scan.
