Homework Help: Math

Posted by Diana on Tuesday, May 17, 2011 at 8:39am.

Alice, Beth, and Charlene start climbing a staircase, each with her left foot on step 1 and then her right foot on the next consecutive step. Alice climbs one step at a time, Beth two steps at a time, and Charlene three steps at a time. Each lands on the top step with her left foot. Compute the minimum number of stairs in the staircase.
I'm not sure how to do this. Should i set up equations?
