Find the missing number Find the missing numbers in the bottom middle circle. (Clue: left halves of the
  central circles relate to the left circles and the right halves to the right circles)


circles are attached in the image  



I am not able to find the numbers with the clue also. Please help.
I hope this helps. This might be giving more than a 'hint' but still.



Sorry for the messiness.
My answer is $6,2$
By using clue we are multiply by the left circles ( like $1\cdot 2$ and $3\cdot 4$ and $5\cdot 6$ we get left central circles values $2$ and $12$ and $30$ respectively)... similar way we use bottom of the left half central circles....then we get the value $6$
Similarly , we divide by the right circles values (like $4÷1$ and $6÷3$ and $9÷3$ we get right half central circles values $4$ and $3$ and $3$ respectively) similarly way we use bottom of the right half of the central circles value is $2$
