How to use Ratio Simplifier
- Enter both ratio components as non-negative whole numbers.
- Run to divide them by their greatest common divisor.
- Copy the reduced ratio, with the original order retained.
How this tool handles your input
Enter two non-negative integers. Both are divided by their greatest common divisor, using BigInt rather than rounded floating-point arithmetic.
Both values cannot be zero. Decimal values must first be scaled to whole numbers using the same factor.
Example: 1920:1080 → 16:9
