Answer 1

The numbers 7, 10, 13, 23, 36, 55, and 67 are classified as prime or composite based on their divisibility by factors other than 1 and themselves.

Step-by-step explanation:

A prime number is a number that is divisible only by 1 and itself, while a composite number is a number that has factors other than 1 and itself. To determine which numbers are prime or composite, we can check if they are divisible by any number other than 1 and themselves.

1. 7 is prime because it is only divisible by 1 and 7.
2. 10 is composite because it is divisible by 1, 2, 5, and 10.
3. 13 is prime because it is only divisible by 1 and 13.
4. 23 is prime because it is only divisible by 1 and 23.
5. 36 is composite because it is divisible by 1, 2, 3, 4, 6, 9, 12, 18, and 36.
6. 55 is composite because it is divisible by 1, 5, 11, and 55.
7. 67 is prime because it is only divisible by 1 and 67.

Based on this information, the correct classification of the numbers is Prime: 7, 13, 23, 67 and Composite: 10, 36, 55.
