Or did you expect people to do your homework?

Oh, I can try to help, and I'll keep on commenting, thank you very much.
Asking for someone else to do something that is obviously homework, where you have put no effort, doesn't really motivate, and is in fact considered cheating.
I also fail to see a specific Matlab question.
Just for kicks, you could submit this:
a = (1:10).';
dummy = perms(a.');
dummy = cumprod(dummy,2);
to_keep = dummy;
dummy = bsxfun(@rdivide,dummy,reshape(a.',1,1,10));
dummy = dummy == floor(dummy);
dummy = sum(dummy,3) == 10;
column = sum(dummy);
column = find(column > 0, 1);
idx = dummy(:,column);
result = min(to_keep(idx,column))
I just love the woefully inefficient. But hey, there are no loops.
And the logic should help.

Since ‘remainder’ is the important requirement, search the MATLAB (link) online help for that term.
