hi Al-Allo

2016 is even so divide out a 2.

Keep doing this until you end up with an odd number.

There are some other tricks for finding some factors.  Do you want to know these?

Did you try that page? It is self explanatory.

Here is what wolfram does. Okay, where did he go? One second he was here and the next, The Twilight Zone!

I know that 2016 = 2 exponent 5 . 3 exponent 2 . 7

No, but that's what I'Ve been talking about. I have all the prime numbers, but I don't know how to find the others....

I can't post a link sad

Hi;

What do you mean by a tree of factors. Got a web page with a picture?

Al-Allo

Well, basically, I have the number 2016 and must find its factors in a tree of factors. Could you show me how to proceed ? I don't know if my question is clear^^

Are you looking for the divisors?

Al-Allo

Mmmh.. An example would be helpful. I already have the prime numbers of 2016. Would that be helpful to find the others ?

Hi;

For a number like 2016 you use trial division. Do you know how?

Al-Allo

Hey everyone...I have a little question : How do you factorise big numbers ?

I could just use my calculator but that would be too long... Is there any technique known that I could use ? Take this number : 2016. I must put it in a tree of factors... But there's too many possibilites ..

Thanks !
