Identify Coefficients and GCF: Identify the numerical coefficients of each term and find their GCF.The numerical coefficients are 14, 70, and 28.To find the GCF of these numbers, list the factors of each:Factors of 14: 1, 2, 7, 14Factors of 70: 1, 2, 701, 7, 703, 14, 705, 70Factors of 28: 1, 2, 280, 7, 14, 28The greatest common factor of 14, 70, and 28 is 14.
Identify Smallest Power: Identify the smallest power of c in each term to find the GCF for the variable part.The powers of c are c3, c4, and c2.The smallest power of c is c2.
Combine GCF for Overall: Combine the GCF of the numerical coefficients with the GCF of the variable part to find the overall GCF.The GCF of the numerical coefficients is 14.The GCF of the variable part is c2.Therefore, the GCF of 14c3, 70c4, and 28c2 is 14c2.
