Their parents where Gaia & Ouranos.

Titan War
When Cronos imprisoned the Hundred-Handed Ones in Tartarus, Gaia Helped Zeus by telling him that the Hundred-Handed Ones held immense strength, and probably even stornger than most Titans, so Zeus released Briareus, Cottus & Gyges, which led to the downfall of the Titans. After the War, the 3 Hekatonheires became the guards at the gates of Tartarus.
