Two dice $\displaystyle A$ and $\displaystyle B$ are rolled. Let the numbers obtained on $\displaystyle A$ and $\displaystyle B$ be $\displaystyle \alpha$ and $\displaystyle \beta$ respectively. If the variance of $\displaystyle \alpha-\beta$ is $\displaystyle \frac{p}{q}$, where $\displaystyle p$ and $\displaystyle q$ are co-prime, then the sum of the positive divisors of $\displaystyle p$ is equal to
