coefficient factors common factors GCF 12 1,2,3,4,6,12 1,2,3,4 4. 20 1,2,4,5,10,20 Step 2. Determine the GCF of the variables. The GCF of the variables is the one with the least exponent and is common to every term. GCF(x3y5, x5y2z) = x3 y2 Step 3. Find the product of GCF of the numerical coefficient and the variables. 4 • 23 y2 = 4 x3y2 This means that, 4 x3 y2 is the GCMF of the two terms 12x3y5 and 20x5y2z. Step 4. Find the other factor, by dividing each term of the polynomial 12x3y5 – 20x5y2z by the GCMF 4x3y2 12x3y5 20x5y2z 4 x3 y2 4x3 ya 4x3y2 . 3y3 4x3y2.5x2z 4 x3 y2 4 x3 y2 → 3y3 – 5x²2 Step 5. Write the complete factored form 12x3y5 – 20x5y2z = 4 x3 y? (3y3 – 5x2z)
