Consider the numbers 13, 16, 27, and 41.
a. Which of these numbers are prime? How do you know?
b. Which of these numbers are composite? How do you know?(2 points)
a. The number 13 is a prime number. This can be determined by checking if it is divisible by any integer greater than 1 and less than itself. Since there are no divisors other than 1 and 13, it is prime.
b. The numbers 16, 27, and 41 are composite numbers. A composite number is a positive integer greater than 1 that has divisors other than 1 and itself.
- The number 16 can be divided evenly by 1, 2, 4, 8, and 16.
- The number 27 can be divided evenly by 1, 3, 9, and 27.
- The number 41 can be divided evenly only by 1 and 41.
