The numerical coefficients of given numerical are 14, 10, 2.

Greatest common factor of 14, 10, 2 is 2.

Common literals appearing in given numerical are x and y

Smallest power of x in three monomials = 2

Smallest power of y in three monomials = 2

Monomials of common literals with smallest power= x²y²

Hence, the greatest common factor = 2x²y²
