In the module "Least common multiple and greatest common divisor word problems", the following ambiguous question was generated:

"At a track and field competition, there are 18 sprinters and 10 long-distance runners and 43 fans. All teams need to have the same number of sprinters and the same number of long-distance runners.

What is the greatest number of teams that can be formed?"

The question does not specify that no runners may be left over. Without that stipulation, 10 could be considered a valid answer.
