You need to make it so that the sum in every row and column will be equal. To do that, you need to select two positive integers. The only numbers that you can place in the grid are those two integers, their sum, their difference, their product, or their quotient. You can place only whole numbers.
Can you complete the grid?

I received an e-mail indicating that one of the posted solutions had a major diagonal that also totaled 86, and requested a search for all such solutions. There are 18 of them:

The other diagonal cannot equal 86 as it has pre-filled two numbers that add to 92.
