Find the greatest common factor (GCF/HCF) of the following polynomials:
The numerical coefficients of given numerical are 7, 21, 14
Greatest common factor of 7, 21, 14 is 7
Common literals appearing in given numerical are x and y
Smallest power of x in three monomials = 1
Smallest power of y in three monomials = 0
Monomials of common literals with smallest power= x
Hence, the greatest common factor = 7x
