By using Android device manager you can do so..

Requirements And Configuration

The Android Device Manager website does require you to sign in with the same Google account that you used on your device, in order to access or track it. That also means that the same account must remain signed in on your device for the remote operations to work, so if someone wipes it entirely and signs in with a different Google account, you’re out of luck.

Upon successfully signing in with the Google account, you’ll be presented with the screen shown above, allowing you to choose any of the devices associated with your account using the drop-down. You are also shown the last located and last used time of the device, as well as its address both written on the card and shown on the Google Maps view. You can use the refresh button at the top-right of the card to manually fetch the latest location of the device.

Also note that while you can remotely ring the device without needing to configure anything on your device itself, remotely locking and erasing it will require that you have activated Android Device Manager as a device administrator on your phone or tablet. To do that, head over to Settings > Security > Device administrators, tap Android Device Manager, and then tap Activate on the next screen.
