Bus A runs every 8 minutes, Bus B runs every 10 minutes, and Bus C runs every 12 minutes. If all three buses leave the station at 8:00 a.m., when is the next time all three buses leave the station at the same time?

Find the least common multiple of 8,10,12.

---

8 = 2^3

10 = 2*5

12 = 3*2^2

---

lcm = 2^3*3*5 = 120

---

120 min = 2 hrs.

Ans: 10:00 am
