The smallest positive integer that is not a factor of 50! is 53 since 53 is a prime. However, since we don't want the number to be a prime, we can multiply 53 by 2 and obtain 106, and 106 will be the smallest positive integer that is not prime and not a factor of 50!.

The sum of the factors of 106 is 106 + 1 + 53 + 2 = 162.
