Find the greatest common factor (GCF/HCF) of the following polynomials:
The numerical coefficients of given numerical are 9, 15, 16, 21
Greatest common factor of 9, 15, 16, 21 is 3.
Common literals appearing in given numerical are x and y
Smallest power of x in four monomials = 1
Smallest power of y in four monomials = 0
Monomials of common literals with smallest power= x
Hence, the greatest common factor = 3x
