How do you solve 3 times 3 magic square numbers 1-9 each row column and diagonal totals a prime number?

Answer 1

To create a 3x3 magic square using the numbers 1-9 where each row, column, and diagonal totals a prime number, you can start by arranging the numbers such that the magic constant (the sum of each row, column, and diagonal) equals 15, which is the only prime number that can be achieved with the numbers 1-9 in a 3x3 configuration. A possible arrangement is:

8  1  6
3  5  7
4  9  2

In this configuration, however, while the rows, columns, and diagonals sum to 15, they do not yield prime numbers. It is impossible to create a 3x3 magic square with this specific property since the sums of rows, columns, and diagonals will always be 15, and the only prime number achievable with the sum of distinct numbers 1-9 is 15. Thus, there is no valid solution.

Answer 2

To create a 3x3 magic square using the numbers 1-9 where each row, column, and diagonal sums to a Prime number, you can start by arranging the numbers so that the magic constant (sum of each row, column, and diagonal) is 15, which is not prime. However, to achieve prime sums, you can explore variations by adjusting the placement of specific numbers. For example, one feasible arrangement is to use the numbers 1, 2, 3, 4, 5, 6, 7, 8, and 9 with specific placements to ensure all rows, columns, and diagonals total to prime numbers like 17 or 19, though achieving this with a strict magic square structure may require deviation from classic arrangements.
