How to simplify a fraction

Example — the form’s default 14/26:

Why 14/26 = 7/13

2×7
2×13

Cancelled 2 = GCF; left 7/13.

Divide the numerator and the denominator by their greatest common factor; what is left shares no prime factor.

FAQ

What does it mean to simplify a fraction?

Simplifying a fraction means rewriting it with the smallest possible numerator and denominator while keeping the same value. For example, 8/12 simplifies to 2/3, because both numbers share a greatest common factor (GCF) of 4.

How do you find the GCF of two numbers?

List the factors of each number (or use prime factorization) and pick the largest one they have in common. For 8 and 12, the common factors are 1, 2, and 4, so the GCF is 4.

Can every fraction be simplified?

No. A fraction is already in its simplest form when its numerator and denominator share no common factor other than 1 - for example, 5/9 cannot be reduced any further, since its GCF is 1.
