If you look at the statement, it says "Triviality of a natural number N is the ratio of the sum of all its proper divisors to the number itself. Recall that a proper divisor of a natural number is the divisor that is strictly less than the number.". Therefore, triviality of 1 should be 0 / 1 == 0, since 1 doesn't have any divisor strictly less than itself. However, I couldn't get an AC (WA4) until I changed the line
if (I == 1) ans = 0
to
if (I == 1) ans = 1.
So, either the statement or the tests are broken.

You must write the number with minimal triviality. Triviality(1) == 0, that means you have to print 1 because 1 is number with minimal triviality. But you try to print the triviality of 1(i.e. 0). The statement is correct.
