Google Chrome should look for and install updates regularly without user intervention. However you can force it to immediately look for applicable updates. To do so, click the three vertical dots ("Customize and control Google Chrome") button in the upper right corner of the browser.

Point at "Help"

Click on "About Google Chrome"

Chrome will immediately look for updates and either tell you that it is up to date, or download and install the necessary updates automatically. If it downloads new updates, you will be presented with a button to "Relaunch" the browser to finish the installation.
