They primes between 30 and 50 are 31, 37, 41, 43 and 47. To find this, first remove all even numbers between 30 and 50 as all even numbers can be made by multiplying 2 and some integer. This leaves. 31, 33, 35, 37, 39, 41, 43, 45, 47 and 49. Next, remove all numbers divisible by 3. This removes 33 and 39 because 3 * 11 = 33 and 3 * 13 = 39. Now, the same thing with 5. Any number that ends in 0 or 5 is divisible by 5, so 35 and 45 can be removed. Now we remove any numbers divisible by 7. 49 is, so we remove it.
To find out if a number is prime, just try dividing it by all prime numbers between 2 and that number (including 2). The easiest method to do this is to write all numbers from 2 to your number down. Then cross out all numbers divisible by 2. Now cross out all numbers divisible by the next lowest number that is not crossed out (which is 3). Repeat this last step (the next number should be 5, then 7, then 11) until you reach your number, or you cross it out. If you have crossed it out, it is not a Prime number, and if it has not been crossed out it is a prime number.

How do you write the prime factorization of numbers?
All composite numbers can be expressed as the product of prime numbers. This is accomplished by dividing the original number by prime numbers until all the factors are prime. A factor tree can help you visualize this. Example: 30 30 Divide by two. 15,2 Divide by three. 5,3,2 Stop. All the factors are prime. 2 x 3 x 5 = 30 That's the prime factorization of 30.
