I assume you mean prime, haha

3. khatyjee

ops sorry i mean prime Factorization

4. frx

Do you know what a primenumber is?

5. khatyjee

no

6. khatyjee

i don't no

7. khatyjee

can u show me how to find it?

8. khatyjee

I have a test on monday.

Well, a prime number is a number which is only divisble by 1 and itself. For example no number other than 1 and 3 divides 3. No numer divides 11 execept 1 and 11, try it out and you will se that is not divisible by any other number.

10. frx

The prime numbers you have to learn is 2,3,5,7,11,13

11. khatyjee

yes it's divaisable by 1,2,5,25

12. khatyjee

okay

13. frx

Then when they want you to factorize by prime numbers you have to find the prime numbers which the number they given you are built from

14. frx

Take 10 for example it's prime factorization is 2*5 since both 2 and 5 are prime

15. frx

The easiest way is to use a "primetree"

16. khatyjee

you mean this |dw:1350154821062:dw|

17. frx

|dw:1350154793229:dw|

18. khatyjee

is that the answer the answer is 2.5.5.5

19. frx

The answer is indeed 2*5*5*5

20. frx

The easiest way to do this is start by testing if 250 is diviseble by 2, and in this case it is then you have 2* 125, right?

21. frx

Since 2 is a prime number you have found what you where searching for so you continue with 125

22. frx

You do the same, is 125 divisible by 2?

23. khatyjee

no

24. frx

So then you go on to the next prime number 3, is 125 divisible by 3?

25. khatyjee

no it divisible by 3

26. khatyjee

by 5

27. frx

Exactly, so then you have 25 left, and as you probobly know 25 is 5*5, so you've got that 2*5*5*5=250

28. frx

Do you get the idea?
