Find the greatest common factor (GCF/HCF) of the given polynomials: 9

1.	Find the greatest common factor (GCF/HCF) of the given polynomials: 9x2, 15x2y3, 6xy2 and 21x2y2
Answer» We know that the numerical coefficients of given numerical are 9, 15, 16 and 21 Greatest common factor of 9, 15, 16 and 21 is 3. Common literals appearing in given numerical are x and y Smallest power of x in four monomials is 1 Smallest power of y in four monomials is 0 Monomials of common literals with smallest power is x ∴ The greatest common factor = 3x

Find the greatest common factor (GCF/HCF) of the given polynomials: 9x2, 15x2y3, 6xy2 and 21x2y2

Answer»

We know that the numerical coefficients of given numerical are 9, 15, 16 and 21

Greatest common factor of 9, 15, 16 and 21 is 3.

Common literals appearing in given numerical are x and y

Smallest power of x in four monomials is 1

Smallest power of y in four monomials is 0

Monomials of common literals with smallest power is x

∴ The greatest common factor = 3x
