How to use this calculator
Simplify a single fraction to lowest terms while seeing the greatest common divisor used in the reduction.
How the calculation works
- Enter numerator and denominator.
- The calculator finds the GCD.
- Both parts are divided by the GCD to produce the simplified fraction.
Formula
Simplified fraction = (numerator / GCD) / (denominator / GCD).
Example
18/24 has GCD 6, so it simplifies to 3/4.
