    There are two bells in the school. Bell A rings every 2 minutes. Bell B rings every 3 minutes. If both bells ring together at 8.02 p.m., when will they ring together again?

    Using our least common multiple calculator, we find the LCM(2, 3) = 6.

    Which means the next time both bells ring together is 6 minutes from now.
    8:02 p.m. + 6 minutes = 8:08 p.m.
