Simply do one thing just like discover the destructive elements of 20.

20/1 = 1 × 20 + 0 (For the reason that the rest is 0, the elements are 1 and 20
20/2 = 2 × 10 + 0 (For the reason that the rest is 0, the elements are 2 and 10)
20/3 = 3 × 6 + 2 (For the reason that the rest is 2, there aren’t any elements)
20/4 = 4 × 5 + 0 (For the reason that the rest is 0, the elements are 4 and 5)
20/5 = 5 × 4 + 0 (For the reason that the rest is 0, the elements are 5 and 4)
20/6 = 6 × 3 + 2 (For the reason that the rest is 2, there aren’t any elements)
20/7 = 7 × 2 + 6 (For the reason that the rest is 6, there aren’t any elements)
20/8 = 8 × 2 + 4 (For the reason that the rest is 4, there aren’t any elements)
20/9 = 9 × 2 + 2 (For the reason that the rest is 2, there aren’t any elements)
20/10 = 10 × 2 + 0 (For the reason that the rest is 0, the elements are 10 and 2)
20/11 = 11 × 1 + 9 (For the reason that the rest is 9, there aren’t any elements)
20/12 = 12 × 1 + 8 (For the reason that the rest is 8, there aren’t any elements)
20/13 = 13 × 1 + 7 (For the reason that the rest is 7, there aren’t any elements)
20/14 = 14 × 1 + 6 (For the reason that the rest is 6, there aren’t any elements)
20/15 = 15 × 1 + 5 (For the reason that the rest is 5, there aren’t any elements)
20/16 = 16 × 1 + 4 (For the reason that the rest is 4, there aren’t any elements)
20/17 = 17 × 1 + 3 (For the reason that the rest is 3, there aren’t any elements)
20/18 = 18 × 1 + 2 (For the reason that the rest is 2, there aren’t any elements)
20/19 = 19 × 1 + 1 (For the reason that the rest is 1, there aren’t any elements)
20/20 = 20 × 1 + 0 (For the reason that the rest is 0, the elements are 20 and 1)

Write down the numbers in blue with out repetition to seek out the elements.
