The correct way is

5 */4 * * * command

That mean the job will run on minute: 5 of every 4 hours

Which means it runs every 240 minutes, not every 245 minutes. – Keith Thompson Mar 30 '16 at 07:50
let set to * */4 * * * command – Tuyen Nguyuen Mar 31 '16 at 10:11
That's even worse. – Keith Thompson Mar 31 '16 at 14:53

Below is correct for Red Hat Based Linux( RHEL,Fedora,Centos etc. ) or maybe on Ubuntu too.

5 */4 * * * command.

But for Solaris Based Operating System, You can use below one :

5 0,4,8,12,16,20 * * * command

But this runs every 240 minutes.

As per your requirement its not possible with normal cron.

You can check the replacement of cron like the one given below:
