Three people participated in races up a staircase. Akvort, the leader, skipped three steps at a time. Barnden, the second participant, skipped four steps at a time, and the last runner, Croft, covered five steps at a time. 

If Akvort won the race and the top landing is also counted as a step, how many steps are in the staircase they raced on?

Note that in the illustration, only the top part of the staircase is shown. There could be hundreds of steps below the drawn portion. However, we need to determine the minimum number of steps that this staircase can contain.
