Actually there are very many people who ask dumb questions in all sorts of areas not just factors and prime numbers. The worst is religion.
I think we need better software to answer multiple questions like What are the factors of 1, 2, 3, 4 . . . n?
The premise of your questions is false: NOT every number is a prime number.
I am guessing you want a divisor that is prime. Then the most obvious one is 13 as 132 is 169
999999999 is not a prime number because it has more factors than 1 and itself. It is obvious that 9 is one of its additional factors.

A prime number is a number which only 1 and itself go into. In this case the obvious ones are 1, 2 and 336. Which mean it is not a prime number because of the 2. (There will be more than them 3 numbers, I just dont want to list them all)
Why don't you start looking for obvious factors. For every 0 in a number, you have a factor of 10 - which has the prime factors 2 and 5.
He is composite, by factorisation of 188: 2* 94 --> 188 Very obvious ... The primes can only have one of the four digits below to be considered a prime number: 1, 3, 7 and 9 The two are the only even number that is prime.
6859. Cube root of 9999 is 21.54, so find the largest prime number less than that (19), then cube that number. 19^3=6,859
In order to find the prime factors of a number, you first divide it by the obvious divisors. In this case, 158 is even so we can divide it by 2. Do that and you get 79. 79 is a prime number so we have finished prime factorizing 158. Thus the prime factors of 158 are 2 and 79.
...I keep finding the same questions that are on geometry extra credit.. the exact same questions. O_o
The prime factors of 34 are 2 and 17.To find the prime factors, it is useful to divide the number by any obvious factors. 34 is even so can divide by 2. Doing this gives us 17. That's a prime number, so cannot be divided any further. Thus, the prime factors of 34 are 2 and 17.
