Finding the prime factorization of a nunber means that all the factors will be prime. For example, 100:

4 X 25 = 100, but 4 and 25 are not prime numbers, so you have to factor them.

4 X 25

2 X 2 X 5 X 5 = 100 All the factors are prime, so this is the prime factorization of 100.

How is prime factorization different from finding factors of a number?

All numbers have factors. Some factors are prime numbers, some are composite numbers, one is neither. When finding the factors of a number, you find all the factors. The prime factorization is a multiplication string of just prime factors that will total the given number.

Prime factorization of 406?

406=2x203203=7x29PF=2x7x29The PF (Prime Factorization) of 406 is 2x7x29.*NOTE: When solving prime factorization, please use a factor tree. They're useful because when you start with a number, you find two factors that together multiplied equal the top number. If one of those factors are composite, find two factors for that number, and keep going until you come to a conclusion where the last number is prime. Therefore, the first factor for each composite factor of the top number, multiplied together, equal the number you started with.

What is the prime factorization of the number in the list which is a multiple of 7 48 72 126?

First, you have to find the number that is a multiple of 7. That number is 126 because 7 x 18 = 126. Then, you need to find the prime factorization. You can do that by starting with any factor pair of 126 and keep factoring the composite factors until all factors are prime. 126: 2 x 61 Since 2 and 61 are prime, that is the prime factorization of 126.
