ChatGPT insists 737 is prime, then proves the opposite in one screenshot

- A screenshot shows ChatGPT confidently claiming 737 is a prime number.
- The reply then walks through the divisibility check badly and even ends with the obviously wrong conclusion that 737 = 11 × 67 is therefore not prime.
- The joke is the model’s overconfident but incorrect reasoning on a basic math question.
