factors math
This is a problem that requires the understanding of the relationship between LCM and GCF. Take the example of 45 and 63: 45=9*5 63=9*7 GCF=9 LCM=9*5*7 So you see that GCF*LCM equals the products of the two numbers. Conversely, LCM/GCF is the product of factors NOT common to ...

find the prime factors of each number. The GCF is the highest power of each prime that they have in common 80=2^4*5 60=2^2*3*5 GCF(60,80) = 2^2*5 = 20 3 is not common to both numbers, so it is not a factor of the GCF.

By inspection, you will find a the GCF. The coefficient of the third term is -1, and the first term does not contain b, so numbers and b are not part of the GCF. Divide each term by the GCF to get the factors: 2a² - 4ab² -ab = a(2a-4b² -b)
