1 and Y
The GCF is Y.
The GCF is Y.
GCF(Y, Y) = Y.
GCF(Y, Y) = Y.
Factor 18 and y then look for the largest common factor form both sets of factors. For example, the factors of 18 are 2,3,6,9,18 if y = 30, then its factors are 2,3,5,6,10,15,30 So the greatest common factor is 6
divide everything by the number/variable all terms have in common. Ex: y^3-y^2-y. The gcf is y, so you would reduce it to y(y^2-y-1)
25xy
Pull out the common factor of 2 ... 2(y^2+6y-16) Then just factor (y^2+6y-16) ... (y-2)(y+8)
That depends on the numerical value of Y.
y4
You take out the common factor, 6. 6y + 18 = 6(y + 3)
The GCF is 2xy.
