Below are sample questions representative of the exercises included on this worksheet and related 4.104 Prime Factorization Using Factor Trees skill assessments:

Problem 1Difficulty: Mastery

You try to build a factor tree for 100, but you cannot split it into two whole-number factors greater than 1. Which prime factorization should you write?

A4 × 5 × 5

B2 × 2 × 5 × 5

C1 × 2 × 5 × 5

D2 × 2 × 5 × 7

Solution & Explanation:One factor tree start is 100 = 2 × 50. Keep splitting any composite factors (like 50 if needed) until all factors are prime. The primes you end with multiply to 2 × 2 × 5 × 5.

Problem 2Difficulty: Mastery

You try to build a factor tree for 99, but you cannot split it into two whole-number factors greater than 1. Which prime factorization should you write?

A3 × 3 × 11

B1 × 3 × 11

C3 × 3 × 13

D3 × 3

Solution & Explanation:One factor tree start is 99 = 3 × 33. Keep splitting any composite factors (like 33 if needed) until all factors are prime. The primes you end with multiply to 3 × 3 × 11.

Problem 3Difficulty: Mastery

You try to build a factor tree for 98, but you cannot split it into two whole-number factors greater than 1. Which prime factorization should you write?

A1 × 7 × 7

B2 × 2 × 7 × 7

C14 × 7

D2 × 7 × 7

Solution & Explanation:One factor tree start is 98 = 2 × 49. Keep splitting any composite factors (like 49 if needed) until all factors are prime. The primes you end with multiply to 2 × 7 × 7.
