Question

factor 15b + 45c + 20d. write your answer as a product with a whole number greater than 1.

Explanation:

Step1: Find GCF of coefficients

Find GCF of 15, 45, 20. Factors of 15: 1,3,5,15; 45:1,3,5,9,15,45; 20:1,2,4,5,10,20. GCF is 5.

Step2: Factor out GCF

Factor 5 from \(15b + 45c + 20d\): \(5(3b + 9c + 4d)\)

Answer:

\(5(3b + 9c + 4d)\)
