- To solve the problem, let's identify the largest number that divides both 1992 and 233 with certain remainders.

- Given conditions:
- 1992 leaves a remainder of 12 when divided by the number.
- 233 leaves a remainder of 13 when divided by the number.

- So, the number should divide:
- \(1992 - 12 = 1980\)
- \(233 - 13 = 220\)

- Find the largest number that divides both 1980 and 220, which is their greatest common divisor (GCD).

- The GCD of 1980 and 220 is 220.

- Therefore, the largest number is 220. ✔️
