This paper decomposes 1992 into the product of the simplest number: 1992 -- > 2 × 996 -- > 2 × 498 -- > 2 × 249 -- > 3 × 83, that is, 1992 = 2 × 2 × 3 × 83. There are two combinations of 1 () 9 () 9 () 2 and 19 () 9 () 2 on the left side of the equation. It is easy to see that 19 () 9 () 2 can not be combined into a multiple of 83 or 83, but can only form 1992 factor 1 = 19-9
