clearvars,clc
found=false; n=0;
while found==false
  n=n+1;
  f=unique(factor(n));
  if length(f)<5
    number=0;
  else
    number=number+1;
    sol(number)=n;
    if number==3;
      disp(sol)
      found=true;
    end
  end
end

finds  1042404     1042405     1042406.

Then inquiring in the Command Window:

>> for i=1:3 factor(sol(i))
end
ans =
     2     2     3    11    53   149
ans =
     5     7    13    29    79
ans =
     2    17    23    31    43

shows the factors themselves.
