Let $ F $ be a field and $ M $ be a maximal subgroup of the multiplicative group $ F^* = F \setminus \{0\} $. It is proved that if $ M $ is divisible, then $ F $ is Euclidean. Furthermore, it is shown that $ F^* $ contains a divisible maximal subgroup if and only if $ F^* $ is isomorphic to the multiplicative group of a real closed field.
