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 point) Write in 1-2 sentences
a. The prime numbers from the list are 13 and 41. We know these numbers are prime because they have exactly two distinct positive divisors: 1 and themselves, and cannot be evenly divided by any other number.
b. The composite numbers from the list are 16 and 27. These numbers are composite because they have more than two distinct positive divisors. Specifically, 16 can be divided evenly by 1, 2, 4, 8, and 16, and 27 can be divided evenly by 1, 3, 9, and 27.
