There are three antique clocks, their hour hands are all missing, only the minute hands are left, and they all move faster, these three clocks are faster by 3 minutes, 6 minutes and 8 minutes per hour respectively. If the minute hands of the three hours are all raised to point to 12 at noon, how many hours later will the minute hands of the three hours point to the same minute number?
有三个古董钟，它们的时针都掉了，只剩下分针，且都走得较快，这三个钟每小时分别快了3分钟、6分钟及8分钟．若在正中午将三个钟的分针都调增指向12，请问至少几小时后三个钟的分针会指向相同的分钟数字？
