Multiply Integer Digits

Multiply Integer Digits takes each number in your list and multiplies its digits together. So if you input 123, you’ll get 1 × 2 × 3 = 6. It works one line at a time, and you can choose whether to keep just the product or show the original number alongside the result. It also gives you options for handling negatives and skipping invalid lines.

You’ll see the output update live as you type, paste, or import content. Everything runs instantly in your browser with no uploads and no delay.

How to Use:

  • Enter one integer per line in the Input Integers box.
  • Or click Choose File to import a supported text file.
  • Choose your Output format:
    • Product only – returns just the result (e.g. 6)
    • Integer → Product – shows both input and result (e.g. 123 → 6)
  • Toggle Treat negatives as positive to ignore negative signs in digit multiplication.
  • Toggle Ignore non-integers to skip any lines that aren’t whole numbers.
  • Toggle Maximize output to expand the result view.
  • Your result appears instantly in the Digit Products box.
  • Use Copy Output to copy the result or Export to File to save it.
  • Click Clear All to reset every field and start fresh.

What Multiply Integer Digits can do:

This tool gives you quick digit-based insights into any list of integers. You can:

  • Reduce a number to a single product of its digits
  • Generate features for numeric data processing or encoding
  • Ignore negative signs while keeping digit structure
  • Skip over lines that aren’t integers entirely
  • View results live and side-by-side if needed

Everything works in real time with flashing output to highlight changes.

Example:

Before:

123
456
-789
1002
abc
42

Output format: Integer → Product Treat negatives as positive: On Ignore non-integers: On

After:

123 → 6
456 → 120
-789 → 504
1002 → 0
42 → 8

Common Use Cases:

Maybe you’re exploring number structure, preprocessing digits for a dataset, or just curious what happens when you multiply them all together. Whether you’re working with logs, exports, or math puzzles, Multiply Integer Digits gives you a fast and easy way to break numbers down by their digits right in your browser.

Useful Tools & Suggestions:

If you’re working with Multiply Integer Digits, try pairing it with Add Integer Digits to see how summing compares to multiplying within the same numbers. You could also run Separate Integer Digits first to clearly view the individual parts before doing any math on them.
