The solver's usage of prime factorization does ensure that cancellations are properly recognized and its use can be viewed as a "best practice". For example, when working with fractions it is not immediately obvious that "91/28" has any cancellations at all, while the prime-factored version, "(7 * 13) / (2*2 * 7)", has an obvious cancellation of sevens.
