6xyz2
4
The possibilities are infinite. One set: 1. 2xy 2. 2x2y 3. 2x4y
9x2
The GCF is 9s3
5x^2
The GCF is 5.
No.
5a and 7b
The two monomials with a greatest common factor of 4M would be 4M and another monomial that includes 4M as a factor. For example, 4M and 12M would have a greatest common factor of 4M. This is because both 4M and 12M can be divided by 4M without a remainder. The greatest common factor represents the largest monomial that can divide evenly into both monomials.
2x and 6x
The GCF is 7y^2.
What makes a greatest common factor "common" is comparing at least two terms and finding something common between them.
