Best Answer

It doesn't matter if the expression is negative, the greatest common factor will still be positive, since you only count the left side of the ladder. When the left side is mutiplied together, it will be positive, because the negative side is on the right side. Therefore, just keep dividing the negative, but it will not affect the common factor
