Ridiculous answer for three examples.

Highlight the Tab you want to keep.
Use a shortcut 'Move tab to left'
Control+Shift+PgUp
Repeat until the tab goes first position.
- Close Tabs to right.
Then select Tab to right Control+PgDn
Close Tab (Repeat this until the tabs are all closed) Control+W
- Close Tabs to left.
-
Select tab to left Control+PgUp

Repeat 1 and 2 alternatively until all the tabs you want are closed.
