Life of me? Is that some type of code name in the house?
But for the "Product" of 2210, you could say that the last number is "2" so we need to find the factors for 1105, which is 1, 5, 13, 17, 65, 85, 221, 1105
So we can multiply all of those numbers to get 1105, but since this every panel needs a 2 digit code, you could say you need
13 x 85 or
17 x 65
13, 17, 85, or/and 65 are the answers for the 1st 2 panels, so if had put the 2 at the end, then you would get the correct answer, but it does not matter anyways because of the rule that you can interchange the numbers and still get the correct answer. I'm sure there are simpler solutions but this is the one I used
