A factor is a number or algebraic expression by which another is exactly divisible. A positive factor is a factor that is a positive number as opposed to a negative one.
The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers or expressions. You have only one expression in the question! The greatest factor of any expression is itself.
Eighty-one quintillion.
3x2 + 6x is ONE expression. A common factor is a factor that is COMMON to two (or more) expressions - not just one. An alternative answer: 3x can be factored out of both of those.
It is written thus: Eight and Eighty-One one hundredths.

(9r - 8)(9r + 8)
(9x + 8)(9x - 8)
To factor out the expression: x2y-y3 First factor out one "y": y(x2-y2) The expression x2-y2 is a difference of squares, which factors as well: (y)(x-y)(x+y) This is the simplest factoring of the original expression.
Nothing is a factor BY ITSELF; you can say that one expression is a factor OF ANOTHER EXPRESSION. IF you don't specify the other expression, the question is meaningless.
x + 81
(3)(3)(3)(3)

An expression is in its lowest terms if the greatest common factor of the numerator and denominator is one.An expression is in its lowest terms if the greatest common factor of the numerator and denominator is one.An expression is in its lowest terms if the greatest common factor of the numerator and denominator is one.An expression is in its lowest terms if the greatest common factor of the numerator and denominator is one.
One such expression is 5n
I think you're mixing a few concepts here. In order to find something in common with something else, you need at least two things. You have only one expression here. The least common factor of any set of integers is 1. I suspect you may want to factor this expression. There is a formula for the difference of squares. This factors to (x - 8)(x + 8) You could compare those factors to the factors of another expression to find something in common between them.
I spell it as eighty-one.
