Answer

Therefore, the members of the set $A^{'}$ are $1, 2, 3$ .

Steps

Step 1 ：Let the universal set U be $U = {1, 2, 3, 4, 5, 6, 7}$ and the set A be $A = {4, 5, 6, 7}$ .

Step 2 ：The complement of set A in the universal set U, denoted as $A^{'}$ , is the set of all elements in U that are not in A.

Step 3 ：So, we need to find all the elements in U that are not in A.

Step 4 ：The elements in U that are not in A are $1, 2, 3$ .

Step 5 ：Therefore, the members of the set $A^{'}$ are $1, 2, 3$ .
