Answer:

\(10m^2n^7\)

Step-by-step explanation:

\(-50m^4n^7 \ and \ 40m^2n^{10}\)

WE need to find GCf for both monomials. GCF is the greatest common factor

\(-50 ->-1 \cdot 5 \cdot 5 \cdot 2\)

\(40 ->2 \cdot 2 \cdot 5 \cdot 2\)

GCF is 2 times 5 =10

GCF of exponent is the lowest exponent

GCF of m^4  and m^2 is m^2

GCF of n^7 and n^10 is n^7

\(-50m^4n^7 \ and \ 40m^2n^{10}\)

GCF is \(10m^2n^7\)
