In the parenthetical citation only the last name of the author is listed.
In the reference list invert the name so the last name comes first.
Smith, Warren Hunting.
In the parenthetical citation both author's last names are listed.
(Smith and Hobart)
In the reference list invert the name of the first author, but not the second.
Smith, Warren Hunting and John Hobart.
Follows the same basic pattern as two authors:
(Smith, Hobart, and Blackwell)
Smith, Warren Hunting, John Hobart, and Elizabeth Blackwell.
When you have four or more authors you need to list all of them in the reference list, but in the parenthetical citation you only need to cite the name of the first author and then write "et al."*.
(Smith, et al.)
Smith, Warren Hunting, John Hobart, Elizabeth Blackwell, Benjamin Hale, Eliphalet Potter, and Murray Bartlett.
*Note: et al. is an abbreviation for the Latin phrase "and others".
