ANSWER

LCD: 28

Step-by-step explanation

To find the LCD we have to write the multiples of the denominators:

$\begin{gathered} 4\colon4,8,12,16,20,24,28,32,36\ldots \\ 7\colon7,14,21,28,35,42,\ldots \end{gathered}$

From those multiples we have to find the first one on the lists that's on both lists. In this case that number is 28, so this is the LCD.
