Factor Trees?

Question

I need factor trees for the following numbers;

30, 42, 18, 50, 24, 45, 84, 66, 80.

But I'm not good at math.

Answer 1

Just keep splitting until you get to all primes...

For example:

... 30
... / . \
..2 ...15
....... / . \
.......3 . 5

So 30 factors to 2 x 3 x 5.


... 42
... / . \
..2 ...21
....... / . \
.......3 . 7

So the prime factors of 42 are 2 x 3 x 7


I think you can take it from here, but let me give you a harder example:

....... 80
...... / .. \
......8 .. 10
...../. \ . /. \
... 4 2. 2. 5
.../.\
.2 . 2

So the factors of 80 are 2 x 2 x 2 x 2 x 5.

It doesn't matter how you split 80 into two factors, as long as you keep splitting numbers that aren't prime.

Answer 5

You can use number 6 to factor 30, 42, 18, 24, 84, 66.
You can use number 5 to factor 50, 45, and 80.

Answer 6

I can't show you on this but i can tell you how to do it...

You take the number, and find 2 numbers that can be multiplied together to equal that number. Then on the two numbers that you just figured out try to see if there are 2 numbers that can equal tone of the numbers number...

Say you have 30...

15 x 2 = 30
? x ? = 2 (2 is a Prime Number it can not be reduced)
? x ? = 15
3 x 5 = 15

So you would have...

30
^
15 2
^
5 3

Now i gave you the first one try to do the rest you'll need to know it for later on...

(PS when you get to a prime number you can't reduce any prime numbers... 1,2,3,5,7 are some that cannot be reduced)

There are many answers for this answer 390 /\ 5 78 /\ 3 26 /\ 2 13 OR 390 390 /\ / \ 39 10 30 13 /\ /\ / \ 3 13 5 2 15 2 / \ 3 5 = 2 common factors: 390= 3x13x5x2 390=3x5x2x13 390 /\ 15 26 / \ / \ 5 3 2 13 there are numeous answers... hope I helped ...

Answer 8

You'll get better by doing your own problems.

I'll do one:
30 = 2*15
15 = 3*5

That's it because 2,3, and 5 are prime.

Answer 9

30-2,3,5
42-2,3,7
18-2,3^2
24-2^3,3
45-3^2,5
84-3,4,7
66-2,3,11
80-2^4,5
