Below are sample questions representative of the exercises included on this worksheet and related 5.25 Prime and Composite Numbers skill assessments:

Problem 1Difficulty: Mastery

Enter 1 if 133 is prime. Enter 0 if 133 is composite.

Solution & Explanation:133 is composite because 133 = 7 × 19.

Problem 2Difficulty: Mastery

June is deciding whether 1369 is prime or composite. Which explanation is correct?

AComposite; 1369 can be written as 37 × 37, so it has a factor besides 1 and itself.

BPrime; because the only factors are 1 and 1369.

CPrime; because 1369 is not a multiple of 10.

DComposite; because 1369 = 38 × 37.

Solution & Explanation:Because 1369 = 37 × 37, 37 and 37 are whole-number factors of 1369. That gives 1369 more than two factors, so it is composite.

Problem 3Difficulty: Mastery

Enter 1 if 247 is prime. Enter 0 if 247 is composite.

Solution & Explanation:247 is composite because 247 = 13 × 19.
