How do the periods of rotation of io europa and ganymeded compare?

Io, Europa, and Ganymede, the three largest moons of Jupiter, have synchronized rotational periods due to a gravitational phenomenon known as orbital resonance. Io has a rotation period of about 1.8 days, Europa takes about 3.5 days, and Ganymede has a rotation period of approximately 7.2 days. This means that for every orbit of Ganymede, Europa completes about two orbits, and Io completes about four, keeping the moons in a stable, resonant relationship with one another.
