To find a prime factor of a number, divide by 2 and see if you get no remainder. Then divide by 3, 4, 5, and so on, until one of the numbers you try gets you no remainder. If no such numbers work below the number you chose, it is prime. In the case of the number 9, 2 does not go into 9, but 3 does.
What does it mean to find the prime factorization of a number?
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.
What is the difference between prime numbers and prime factor?
A prime number is any number which has only 2 factors. That is, a number that can divide only by itself and 1. For example, 29 is a prime number, as it cannot divide evenly by any number other than itself and 1. A factor of a number is any number which that original number can divide by evenly. For instance, 24 can divide by 8, so 8 is a factor of 24. However, 8 isn't prime so it isn't a prime factor of 24. The prime factors of 24 would be 2, 2, 2 and 3.
