This is connection to the Euclidean algorithm.
Euclidean algorithm:
i a(i) b(i) Cbit(i) 0 36 23 1 13 23 1 2 13 10 1 3 3 10 1 4 3 7 0 5 3 4 0 6 3 1 1 7 2 1 0 8 1 1 1
Table formula: if min[a(i1);b(i1)] = max[a(i);b(i)] then Cbit(i)=1 if min[a(i1);b(i1)] = min[a(i);b(i)] then Cbit(i)=0
if a(i1)=max[a(i1);b(i1)] then a(i)=a(i1)b(i1) else a(i)=a(i1); if b(i1)=max[a(i1);b(i1)] then b(i)=b(i1)a(i1) else b(i)=b(i1);
