Question

What is the Greatest Common Factor of x4 and x3?

x
x2
x3
x4
@Directrix

Answer 1

This one i have no idea

Answer 2

If i had to pick i would pick A

Answer 3

It is as if you had( x4+ x3_ and were asked to factor out a monomial.

Answer 4

No, it is a factor, but not the greatest.

Answer 5

then
D

Answer 6

No, I don't believe so.

Let's see what @Directrix has to say. I think I'm confused, the answer may be A.

Answer 7

So, look at x^4 and look at x^3 and see what is the greatest power of x common to both x^3 and x^4.

Answer 8

Oh wait, yeah A is incorrect.

Answer 9

So is D..

Answer 10

@knightmare6 You are saying x^4.

So if you factored x^4 out of this ( x4+ x3), how would it look.

( x^4+ x^3) = x^4 ( x ^ ? + x ^ ?)

Answer 11

*Hint*

Multiplying 'x' adds an exponent.

Answer 12

So if you have:

\(x^{10}\)

Multiplying 'x' gives you:

\(x^{11}\)

Answer 13

i have no idea..

Answer 14

The "Greatest Common Factor" is the largest of the common factors (of two or more numbers)

Answer 15

Hmm..I don't know how to explain..

Remember, you multiply to get factors..

And multiplying an 'x' adds an exponent..

So what's \(x^3 * x\)?

Answer 16

x^4.

Answer 17

Not LCM, that is a different concept.

Answer 18

well x^4 is the greatest of the two but if they both have ot equal a number then x^12 is the gcf

Answer 19

iGreen is doing LCM and not GCF which has messed up this thread.

Answer 20

Wait..what?

Answer 21

I'm all messed up..sorry @knightmare6

Answer 22

Its all good dont worry about it.
