Since 7y is common to both factors, therefore 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
From the factors above, it is clear that 7 and y are the greatest common factors.

Factor out
- 21xy=3×7×y×x
- 14y=2×7×y
So
- 7y is common hence 7y is GCF
Now factor up
- 7y(3x+2)
