Let be a number field, then each fractional ideal
of
belongs to an equivalence class
consisting of all fractional ideals
satisfying
for some nonzero element
of
. The number of equivalence classes of fractional ideals of
is a finite number, known as the class number of
. Multiplication of equivalence classes of fractional ideals is defined in the obvious way, i.e., by letting
. It is easy to show that with this definition, the set of equivalence classes of fractional ideals form an Abelian multiplicative group, known as the class group of
.
