How to finish multiple activities on a button click?

I am implementing android application which is on web service. I'm creating login Activity A then homepage Activity B and so on.

Suppose there are A, B, C, D and E etc. activities. I'm creating a home button in Activity E and by clicking on that Activity E, D and C should finish and home Activity B should resume.

How can I implement that?

A > B > C > D > E > back button in E Activity > B.
