The prime factors of 250 are 2 and 5.
2x5x5x5
250 = 2*5*5*5 = 2*53
It would probably be easier to say that all numbers between 2 and 250 with the exception of the numbers 121, 143, 169 are divisible by the numbers 2,3,5, or 7. Explanation: One of the basic rules of math called the "Fundamental theorem of arithmetic" states that all numbers can be written as a product of prime numbers. 2, 3, 5, and 7 are the first four prime numbers. We also know that at least one of the numbers multiplied has to be less then 16. This is because the square root of 250 is about 15.81. If more then one of the numbers were larger then 16, then the result would be greater then 250. Example = 16*16 = 256. So now we know that all numbers between 2 and 250 are divisible by prime numbers that are less then 16. These numbers are "2,3,5,7,11,13." If you notice the first four numbers in that list are the numbers that you gave. This means that the only numbers between 2 and 250 that aren't divisible by 2, 3, 5, and 7 are the numbers (11*11), (11*13), and (13*13) or 121, 143, 169.
No, there are more normal numbers than prime numbers. Since 2, 3, 5, 13, and 19 are some examples of prime numbers, those only seem to be a few. Remember, numbers can stretch as far as someone wants, so 1,000 isn't a prime number, since you can have 250 and 4 to multiply into it, and 250 and 4 aren't prime numbers. Since the number scale can go on forever, there are more real numbers than prime numbers.
