One sentence. One number. One brutal answer.

I’m thinking of a number between 1 and 1,000,000. It satisfies exactly one of the following statements:

1.The number is a multiple of 3.

2.The number is a square number.

3.The number is prime.

4.The number contains the digit 7.

5.The number is none of the above.

What’s the number?

Note: Only one of those five statements is true for the number. There’s exactly one number between 1 and 1,000,000 that fits this. What is it? (have objective answer)
