write the prime factorization of 45. order the factors from least to greatest (for example, 2 × 2 × 3 × 5).
write the prime factorization of 45. order the factors from least to greatest (for example, 2 × 2 × 3 × 5).
Answer
Explanation:
Step1: Divide by smallest prime factor
Divide (45) by (3) (smallest prime factor of (45) other than (1)): (45\div3 = 15).
Step2: Divide the quotient
Divide (15) by (3): (15\div3=5).
Step3: Analyze the last quotient
Since (5) is a prime number, we stop.
Answer:
(3\times3\times5)
