You try if the number is divisible by any smaller number (except one). If it isn't, it is a prime number. In practice, it is enough to test divisibility by factors up to the square root of the number.You try if the number is divisible by any smaller number (except one). If it isn't, it is a prime number.

No. A prime number is divisible only by itself and 1. Squares have other factors.
No, 7 * 7 + 1 = 50, which is divisible by 2 and 5.
A number that is divisible by 4.
no, a square is a number times its self, not a number divisible by 2.
NO! It is a number times itself, so it has to be divisible by that number.
No, never. It would be divisible by the prime number.

33 is not as it is divisible by 3 and 11 1 is because the only thing 1 is divisible by is itself, making it the only prime number to be a perfect square.

No, 7 * 7 + 1 = 50, which is divisible by 2 and 5.
Converse:If a number is divisible by 3, then every number of a digit is divisible by three. Inverse: If every digit of a number is not divisible by 3 then the number is not divisible by 3? Contrapositive:If a number is not divisible by 3, then every number of a digit is not divisible by three.
