Is it possible to download GTA Online without the main GTA game?

GTA Online is an integral part of the Grand Theft Auto V experience and cannot be downloaded independently. To play GTA Online, one must purchase Grand Theft Auto V, as the online component is included with the main game. After installing GTA V, players can access GTA Online through the game's menu. There is no separate standalone version or digital download available for just the online component without the base game of Grand Theft Auto V.
