How are fractions reduced to their lowest terms

Fractions can be simplified by dividing the numerator and denominator by their greatest common factor. This is how this calculator does it.

When reducing fractions by hand it may be easier to repeatedly divide numerator and denominator by factors that are common to both of them. The process is complete when the numerator and the denominator have no more factors in common.

Reduced fractions are fractions that have been reduced to their simplest form. When the GCF of the numerator and denominator is equal to 1, the fraction cannot be reduced any further.
