The answer to this question a single digit integer, ranging from 1 to 4 (both inclusive). On subtracting 2 from the unit place digit of H.C.F. of 2 2 × 3 2 × 5 3 × 7, 2 2 × 3 3 × 5 2 × 7 2 and 3 × 5 × 7 × 11, we get

Answer:
Let the letters a, b, and c stand for integers (that is, whole numbers).
Always choose a so that it larger than the sum of b and c. That is, a > b + c. This guarantees no entries in the magic square is a negative number.
Do not let 2 X b = c. This quarantees you won't get the same number in different cells.
Using the formulas in the table below, you can make magic squares where the sum of the rows, columns, and diagonals are equal to 3 X whatever a is.
a + c
a + b - c
a - b
a - b - c
a
a + b + c
a + b
a - b + c
a - c
To create the first Magic Square #15 above, you let a be equal to 5, let b be equal to 3, and let c be equal to 1. Here are some others:
a = 6, b = 3, c = 2
a = 6, b = 3, c = 1
a = 7, b = 3, c = 2
a = 7, b = 4, c = 2
a = 8, b = 6, c = 1
a = 8, b = 5, c = 2
a = 8, b = 4, c = 3
