Formula: Divide numerator and denominator by their GCD

Fraction Simplifier: Reduce Fractions to Lowest Terms

Simplify any fraction by dividing numerator and denominator by their greatest common divisor. See both the reduced fraction and its decimal value.

Formula

Find GCD of numerator and denominator. Divide both by the GCD. If denominator is 0, display an error message.

Worked example

42/56: GCD(42, 56) = 14. Reduced fraction: 3/4. Decimal value: 0.75.

Practical guidance

Avoiding denominator zero

A fraction with denominator 0 is undefined. The calculator detects this and shows an error rather than computing an invalid result. If your fraction has a zero denominator, check the original problem — you may need a different approach.

Negative fractions

The calculator handles negative numerators and denominators. A negative over a negative simplifies to a positive fraction. The GCD is calculated from absolute values, preserving the correct sign in the result.
