The steps
See it
To simplify a fraction, divide the numerator and denominator by their greatest common factor (GCF). When the GCF is 1, the fraction is already in lowest terms.
FractionSteps shows the GCF it found and the division step, so reducing isn't a mystery.
Worked examples
Frequently asked
What does it mean to simplify a fraction?
It means rewriting the fraction with the smallest possible whole numbers on top and bottom while keeping the same value, by dividing both by their greatest common factor.
How do I find the greatest common factor?
Find the largest number that divides both the numerator and denominator evenly. FractionSteps computes it for you and shows it in the steps.
Is 3/4 already simplified?
Yes. 3 and 4 share no common factor above 1, so 3/4 is already in lowest terms.
