Advanced Divisibility Calculator

Quickly determine if a number is divisible by others with our powerful and interactive Divisibility Calculator. This tool offers a dual-function analysis: check a number against a custom list of divisors, and simultaneously see which common divisibility rules it satisfies. Results are calculated and displayed in real-time, providing instant, detailed feedback including quotients and remainders.

How It Works

Our calculator is designed for instant analysis and clarity. The tool is split into two main functions that work together.

  1. Enter the Main Number: Input the number you want to check (the dividend) into the top field.
  2. Provide Divisors: Type a list of numbers to test against (the divisors) in the second field, separated by commas, spaces, or line breaks.
  3. Analyze Instant Results: The tool automatically displays a card for each of your divisors, showing if it's divisible and the result. It also shows which common math rules (like for 2, 3, 5, etc.) the main number passes.

Key Features

  • Dual-Function Analysis: Uniquely checks your number against both a custom list of divisors and a built-in set of common divisibility rules.
  • Detailed Per-Divisor Breakdown: For each number in your custom list, it shows:
    • A clear "Yes" or "No" result with an icon.
    • The exact quotient and remainder for every check, not just a simple pass/fail.
  • Common Divisibility Rules Checker: A dedicated panel automatically tests your number against the rules for divisibility by 2, 3, 4, 5, 6, 9, and 10, highlighting which ones are met.
  • Real-Time Calculation: No submit button needed. All results update instantly as you type in either input field.
  • Dynamic Summary: A clear summary at the top tells you exactly how many of your custom divisors the number is divisible by (e.g., "120 is divisible by 7 of your 10 numbers").
  • Flexible Input Parsing: The divisors list intelligently accepts numbers separated by spaces, commas, or newlines, and automatically handles duplicates.

How to Use the Calculator

  1. Step 1: Enter the Number to Check
    Type the main number (dividend) into the first input box.
  2. Step 2: Enter Your List of Divisors
    In the second input box, type the list of numbers you want to test for divisibility.
  3. Step 3: Review the Results
    The page will instantly update. Review the summary, the individual cards for your custom divisors, and the "Common Divisibility Rules" panel to see a complete analysis.
  4. Step 4: Clear to Restart
    Click the "Clear" button to easily reset both fields and start a new calculation.
