which number is a prime number 7 8 9 or 10
The number 7 is a prime number.
To determine if a number is prime, we need to check if it is divisible by any number other than 1 and itself.
Let's evaluate the numbers given one by one:
1. Number 7:
To check if 7 is prime, we need to check if it is divisible by any number other than 1 and 7. Since 7 is not divisible by 2, 3, 4, 5, or 6, it is only divisible by 1 and itself. Therefore, 7 is a prime number.
2. Number 8:
To check if 8 is prime, we need to check if it is divisible by any number other than 1 and 8. Since 8 is divisible by 2 and 4, it is not a prime number.
3. Number 9:
To check if 9 is prime, we need to check if it is divisible by any number other than 1 and 9. Since 9 is divisible by 3, it is not a prime number.
4. Number 10:
To check if 10 is prime, we need to check if it is divisible by any number other than 1 and 10. Since 10 is divisible by 2 and 5, it is not a prime number.
From the options given, the only prime number is 7.
