How do you delete incoming & outgoing calls on HTC M8 One Android Phone?

[Android Central Question]

I tried to get an answer here before and did not go anywhere so I will try again with this question.

Can somebody tell me how to delete the incoming & outgoing phone numbers that have gone before in my HTC M8 One Android Phone?

Any answers will be truly appreciated.

Thank you
