`brain teaser.

Moon Dance

On the planet Mathemarvia, there are two beautiful moons. Oin is purple and Datu is gold. Oin is full every 32 Mathemarvian days, while Datu moves more slowly and is full only every 44 Mathemarvian days. The moons are named after a famous couple in an ancient legend. According to the legend, the couple is allowed to dance together only when both moons are full on the same night.

If both moons are full tonight, how long will it be until Oin and Datu dance again?
