Given the numbers 12433, 11292, 1882, 17, and a variable
?
x, let's try to construct a
3
×
3
3×3 magic square. To do so, we need to determine the correct value for
?
x and place the remaining numbers appropriately.

A
3
×
3
3×3 magic square has the following properties:

The sum of each row, column, and diagonal must be equal.
The magic constant
?
M for a
3
×
3
3×3 magic square can be found by summing all the given numbers plus
?
x and dividing by 3.
Given numbers:

?

12433
a=12433
?
=
11292
b=11292
?
=
1882
c=1882
?

d=17

e=x
We need to find the remaining 4 numbers to complete the magic square.

Let's set up the magic square and solve for

First, calculate the magic constant
?
M:

?
=
12433
+
11292
+
1882
+
17
+
?
+
(remaining 3 numbers)
3
M=
3
12433+11292+1882+17+x+(remaining 3 numbers)
​

Since there are 9 positions in the magic square, let’s determine the value of
?
M for each row, column, and diagonal to be equal.

We have the initial sum:

?
=
12433
+
11292
+
1882
+
17
+
?
S=12433+11292+1882+17+x
?
=
25624
+
?
S=25624+x

Thus, the magic constant
?
M is:

?
=
25624
+
?
3
M=
3
25624+x
​

To balance the sum of each row, column, and diagonal to
?
M, we must ensure all sums equal
?
M.

Let’s fill the remaining grid and solve:

By solving for
