I heard the bells on Christmas dayTheir old familiar carols play,And wild and sweet the words repeatOf peace on earth, good will to men.

I thought how, as the day had come,The belfries of all ChristendomHad rolled along th’unbroken songOf peace on earth, good will to men.

And in despair I bowed my head:“There is no peace on earth,” I said,“For hate is strong and mocks the songOf peace on earth, good will to men.”

Then pealed the bells more loud and deep:“God is not dead, nor doth he sleep;The wrong shall fail, the right prevail,With peace on earth, good will to men.”

Till, ringing, singing, on its way,The world revolved from night to day,A voice, a chime, a chant sublime,Of peace on earth, good will to men!

Spoiler alert…the top row is 5 2 1 10 6 4 9 8 3 7 right? Fun!

Yes.
I design the puzzles to have only one solution so you can be sure that if the factors you find work, then you have found the correct solution. About a week after I publish the puzzles, I update the posts with either the correct factors or a table showing a way to arrive at the correct solution logically.
