Question

select all the numbers that are not composite.
17 37 41 13
submit

Explanation:

Step1: Recall composite number definition

A composite number is a positive integer that has at least one positive divisor other than 1 and itself. Prime numbers (and 1, but 1 is neither prime nor composite) are not composite. Prime numbers have exactly two distinct positive divisors: 1 and themselves.

Step2: Analyze each number

• 17: Divisors are 1 and 17. So it's prime (not composite).
• 37: Divisors are 1 and 37. So it's prime (not composite).
• 41: Divisors are 1 and 41. So it's prime (not composite).
• 13: Divisors are 1 and 13. So it's prime (not composite).

Answer:

17, 37, 41, 13 (all these numbers are prime, hence not composite)
