CollectCommonFactors(AngouriMath.Entity)

Method (no overloads)

Summary

Pulls a shared factor out of the terms of a sum: a*c + a*d + b*c + b*d becomes a*(c + d) + b*(c + d), which the pairwise rules above close to
(a + b) * (c + d) on the next pass.

Remarks

The pairwise rules only ever see two adjacent terms of the sum tree, so a sum of
four was left half-factored at a*(c + d) + b*c + b*d -- that is
https://github.com/asc-community/AngouriMath/issues/531. Sums
of two are left to those rules, which are older and better tested.
Internal so the data form of this set calls it rather than repeating it.

Returns

null when no factor is shared, so the rule does not fire.
