How do you find the GCF of #2y, 10y^2#?

Answer 1

Genesis Amaya

GCF: #2y#

Given: #2y " & " 10y^2#, Find GCF (Greatest Common Factor)

Factors of first expression: #2 * y#

Factors of second expression: #2 * 5 * y * y#

Factors that are common to both expressions: #2 " & "y#

GCF: #2y#

To find the greatest common factor (GCF) of (2y) and (10y^2), you identify the highest power of each common factor that appears in both terms.

For (2y) and (10y^2), the common factor is (y), and the highest power of (y) that appears in both terms is (y^1) in (2y).

So, the GCF of (2y) and (10y^2) is (y).
