LCM Calculator

Calculate the Least Common Multiple (LCM) of multiple numbers using prime factorization and Euclidean methods. Includes GCD, ratio analysis, batch processing, and visual representations.

Key Features

  • • Calculate LCM using prime factorization method
  • • Compute LCM via Euclidean algorithm
  • • Compare results using both methods
  • • Automatically calculates GCD
  • • Displays LCM/GCD ratio
  • • Batch processing (CSV or text input)
  • • Step-by-step explanation of calculations
  • • Interactive charts (prime factors & multiples)
  • • Calculation history with export (CSV, JSON, PDF)
  • • Visual timeline of multiples

Use Cases

  • • Finding common denominators in fractions
  • • Scheduling recurring events
  • • Engineering & signal synchronization
  • • Mathematical problem solving
  • • Programming and algorithm optimization

How It Works

  • • Enter two or more positive integers
  • • Choose calculation method (prime, Euclidean, or both)
  • • System calculates GCD internally
  • • Applies LCM formula: LCM = (a × b) / GCD
  • • Displays results with detailed steps
  • • Visualize results using charts and timelines
