Below are sample questions representative of the exercises included on this worksheet and related 5.28 Prime Factorization skill assessments:

Problem 1Difficulty: Mastery
Use the division-ladder visual for 1764. Which final prime factorization is shown?
A22 × 32 × 72
B2 × 3 × 7 × 42
C4 × 9 × 49
D23 × 32 × 7
Solution & Explanation:The ladder reaches prime divisors 2, 2, 3, 3, 7, and 7. Grouping repeated factors gives 22 × 32 × 72.
Problem 2Difficulty: Mastery
Why is 12 × 45 not a final prime factorization of 540?
ABoth 12 and 45 are composite, so they must be broken into primes.
BThe product 12 × 45 does not equal 540.
CPrime factorizations must include a decimal point.
DThe factor 45 is prime, but 12 is not.
Solution & Explanation:The product 12 × 45 equals 540, but 12 and 45 are composite. Breaking them down gives 22 × 33 × 5.
Problem 3Difficulty: Mastery
Which whole number is equal to 25 × 3 × 52?
A1200
B1800
C2400
D3600
