I assume you mean prime, haha
ops sorry i mean prime Factorization
Do you know what a primenumber is?
i don't no
can u show me how to find it?
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.
The prime numbers you have to learn is 2,3,5,7,11,13
yes it's divaisable by 1,2,5,25
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
Take 10 for example it's prime factorization is 2*5 since both 2 and 5 are prime
The easiest way is to use a "primetree"
you mean this |dw:1350154821062:dw|
is that the answer the answer is 220.127.116.11
The answer is indeed 2*5*5*5
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?
Since 2 is a prime number you have found what you where searching for so you continue with 125
You do the same, is 125 divisible by 2?
So then you go on to the next prime number 3, is 125 divisible by 3?
no it divisible by 3
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
Do you get the idea?
