Resize filesystem

For the disk

Disk /dev/vda: 1636GB

this is the result from parted print free command.

 3      427GB   1100GB  673GB   primary   ext4
        1100GB  1636GB  537GB             Free Space

The primary ext4 filesystem is mounted at let say /example.

How should i resize the filesystem to take over all the remaining space (total of ~1.1TB)? The filesystem is up and running.

Thanks in advance…
