1. Point({1 - mover, 0}) → f2Point
2. Point({-1 + mover, 0}) → f1Point
3. Polygon(f1Point, f1Point + (f1, 0), f1Point + (f1, 1), f1Point + (0, 1)) → f1poly, f1point, n, p, q
4. Polygon(f2Point, E, G, H) → poly3, f2point, e, g_1, h_1
5. Textfield(f1Text) → InputBox1
6. Textfield(f2Text) → InputBox2
7. IndexOf(47, TextToUnicode[f1Text]) → slash1
8. IndexOf(47, TextToUnicode[f2Text]) → slash2
9. Take(f1Text, slash1 + 1) → D1Text
10. Polygon(f1Point, f1Point + (1, 0), 4) → poly1, f, g, h, i, A, B
11. Polygon(f2Point, f2Point + (1, 0), 4) → poly2, j, k, l, m, C, D
12. Take(f2Text, slash2 + 1) → D2Text
13. Sequence(Segment[f1Point + (i / D1, 0), f1Point + (i / D1, 1)], i, 1, D1 - 1) → f1Bars
14. Sequence(Segment[f2Point + (0, i / D2), f2Point + (1, i / D2)], i, 1, D2 - 1) → f2Bars
15. Polygon(f2Point, f2Point + (0, f2), f2Point + (1, f2), f2Point + (1, 0)) → f2poly, r, s, t, a
16. RemoveUndefined(Sequence[If[pN / i ≟ floor(pN / i), i], i, 1, pN]) → Nfactors
17. RemoveUndefined(Sequence[If[pD / i ≟ floor(pD / i), i], i, 1, pD]) → Dfactors
18. Intersection(Nfactors, Dfactors) → factors
