GCF of 2 or more term is the product of the common factors with lowest exponents:
X^3 Y^2 + X^2 Y^2 + X^2 Y (1)
X^2 Y is the GCF of the terms of the above expression:
To Factor the above expression:
X^2 Y ( XY + Y + 1) (2) / Pullout the GCF and open parenthesis and divide each term by GCF
Factoring is opposite of distributive law:
Multiplying the expression (2) by use of distributive law , will result in expression (1)
