  1. 14x^2+8x+72: GCF is 2, the only common factor of the coefficients
  2. 3x^4-12x^3: numerical GCF is 3, algebraic GCF is x³, so GCF=3x³
  3. 7x+28x^2-35x^3: numerical GCF=7, algebraic GCF=x, GCF=7x
  4. 24x^4-6x: numerical=6, algebraic=x, GCF=6x
  5. 39x^5+13x^3-78x^2: numerical 13, algebraic x², GCF=13x²
  6. 145x^9-17: GCF=1 (no common factor)
  7. 6x^6-3x^4-9x^2: GCF=3x²
  8. 72x^9+15x^6+9x^3: GCF=3x³
  9. 6x^4-18x^3+15x^2: GCF=3x²
