How does prime factorization help find all the factors of a number?

If you know the prime factorization of a number, you can find out the total number of factors.
Example: 210
21 x 31 x 51 x 71 = 210
Add one to the exponents and multiply them.
2 x 2 x 2 x 2 = 16, the total number of factors.
You know that 1, 2, 3, 5, and 7 are factors. You need three more to get halfway.
2 x 3 = 6
2 x 5 = 10
2 x 7 = 14
Divide all those numbers into 210.
1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210

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.
How do you find the sum of the distinct prime factor of a number?
Find the prime factorization. Identify the distinct prime factors. Add them up.
What is the number if the prime factorization is 2x2x7x13?
To find the number, multiply the factors. The answer is 324.
Find the prime factorization of the numbers 33?
The prime factorization of the number 33 is: 3 x 11
What are the prime factors of 40?
The prime factors of 40 are 2 and 5 To find the prime numbers of 40, you can find its prime factorization. Start with any two of its factors, such as 8 X 5. 5 is a prime number, but 8 can be factored into 4 X 2. 2 is a prime number, but 4 can be factored into 2 X 2. The prime factorization of 40 is 2 X 2 X 2 X 5, so the prime numbers in 40 are 2 and 5.

What is prime factorization in math?
its when you find the factors of a prime number and multiply them by 10.
Is it easier to list the factors of each number and compare or to find the prime factorization of each number and multiply common factors?
it is easier to find the prime factorization because you do not have to keep multiplying over and over and over again!!!!
Find the prime factorization for 101?
101 is already prime; no factorization required.
How do you find the sum of the distinct prime factor of a number?
Find the prime factorization. Identify the distinct prime factors. Add them up.
How do you prime 55?
To find the prime factorization of a number, start with any factor pair of that number and keep factoring the composite numbers until all factors are prime. 55 5 x 11 = 55 Both factors are prime, so that is the prime factorization.
How many ways can you find the prime factorization of a number?
Divide it by each prime number which does not have remainder.
Will prime factorization help find the number of factors of any number?
Write the prime factorization with exponents. Add 1 to each exponent. (Numbers without exponents actually have the exponent 1.) Multiply them together. That will be the number of factors.
How do you find coprimes of a number?
First, find the prime factorization of the number. For instance, with 45: 45 = 3 * 3 * 5 = 32 * 51 Now, from this prime factorization, any numbers whose prime factorizations do not include these factors is coprime to the number you have.
