Story Problem - Factoring
An "A" train leaves a subway station every 13 minutes. An "E" train leaves evry 9 minutes. If both trains just left the station on parallel tracts, when will both leave the station together again?
Answered by Steve
Since LCM(9,13) = 9*13 = 117
After 117 minutes,
9 A trains will have left,
13 E trains will have left
and then the cycle starts over.

Trains run on tracks, not tracts.
