Since 7y is common to both factors, hence the GCF of the expression is 7y. The factored form will be 7y(3x + 2)

Greatest common factor of an expression

The greatest common factor is the value that will divide an expression without leaving a remainder.

Given the expression 21xy + 14y

Find the factors

21xy = 7 * 3 * x * y

14y = 7 * 2* y

Since 7y is common to both factors, hence the GCF of the expression is 7y. The factored form will be 7y(3x + 2)
