Did you try the calculator on this site?

1 - Press "2nd" key in the top left-hand corner.

2 - You should see a key labled "mod" to the right.

3 - Enter your first number, 512, then "mod" key followed by 6. Does it give you the remainder of 8?

4 - If you don't get 8, repeat the procedure: 512 mod 12. Does it give you the remainder of 8?

5 - If it does, go to the next number: 430 mod 12. Does it give you the remainder of 10?

6 - If it does, go to the next number: 489 mod 12. Does it give you the remainde of 9?

7 - If it gives the remainders of: 8, 10 and 9, then your "modulus" is 12, or B.......and so on.

8 - Good luck to you.
