2xy
The GCF is 2x.
The GCF is 4xy
The GCF is 4xy.
Since 4xy2 is a factor of 20x2y4, it is automatically the GCF.

The GCF is 4xy^2
The GCF is 4xy.
2xy
The GCF is 4xy.
Since 4xy2 is a factor of 20x2y4, it is automatically the GCF.
4x2yz + 2xy2z + 2xyz = 2xyz(2x + y + 1) Not sure what check mentally entails.
4xy
x(2yz) = 2xyz
