An irreducible fraction, also known as a simplified fraction, is one in which the numerator and denominator have no common factors beyond 1. In other words, it cannot be further simplified without altering its value.

To achieve this, both the numerator and denominator are divided by their greatest common divisor.
An irreducible fraction is in its simplest form and is useful in mathematics for representing proportional relationships clearly and concisely.
