: Yup, found that too, and wrote this before I saw your post: The factors of 19175641 aka 29*29*151*151 are {1,29,151,841,4379,22801,126991,661229}, aka {1,29,151,29*29,29*151,151*151,29*29*151,29*151*151}, which sum to 816422, in case that helps. It might beinteresting that the "naughty boy" is a product of so few primes. --[[User:Petelomax|Pete Lomax]] ([[User talk:Petelomax|talk]]) 11:50, 11 February 2021 (UTC)
