                An “A” train leaves a subway station every 10 minutes. An “B” train leaves every 12 minutes. An "C" train leaves every 15 minutes. If all trains just left the station on parallel tracks, when will they arrive at the station together again?

    you want to find the least common multiple of the times.
10 = 2*5
12 = 2^2 * 3
15 = 3*5
the LCM will have the highest power present for each prime factor
LCM(10,12,15) = 2^2 * 3 * 5 = 60
    
10 = 2*5
12 = 2^2 * 3
15 = 3*5
the LCM will have the highest power present for each prime factor
LCM(10,12,15) = 2^2 * 3 * 5 = 60
