Объяснение:

${\begin{array}{l}{\begin{array}{r|r}138&2 \\ 69&3 \\ 23&23 \\ 1&\; \\ \end{array}} \\ {\begin{array}{l}\phantom{8} \\ \end{array}} \\ \end{array}}&{\begin{array}{l}{\begin{array}{r|l}28&2 \\ 14&2 \\ 7&7 \\ 1&\; \\ \end{array}} \\ {\begin{array}{l}\phantom{8} \\ \end{array}} \\ \end{array}}$
