$5(k^3+4k^2-3)$
Find the greatest common factor. Find the prime factors of each term and multiply the factors that are common to all the terms. $5k^3=\underline 5\times k\times k\times k$ $20k^2=\underline 5\times2\times2\times k\times k$ $15=\underline 5\times3$ GCF $=5$ Factor the GCF out of each term. Use the factors from each term that are not part of the GCF. $5k^3+20k^2-15=5(k^3+4k^2-3)$
