There are factor trees and ladders and rainbows and fireworks and they're all pretty much the same thing: ways to notate the process of finding the prime factorization of a given number. They differ in where they write the number and where the factors end up. In a factor tree, write the original number at the top and the bottommost branch will be the prime factorization. In a factor rainbow, write the original number at the bottom and the prime factorization will be the uppermost arc.

What are the prime factors and prime factorization?

All numbers have factors. Some factors are prime numbers. These are prime factors. A factor string where all the factors are prime numbers is called a prime factorization.

Is 8855162322347449101830271721201913 a prime number?

No. The prime factorization of this number is37x2011x3673x9919204957x3266517126331619.If you want to check the primeness of some big number X, you can go to and type in "Is X prime?" You can also get the prime factorization by typing in "Factor X".

What is the prime factorization of 23?

23 is a prime number so there is no prime factorization. Some consider it to be acceptable to write 1 X 23 in order to show the number is prime, even though 1 is not a prime or composite number.23 is already prime.

Define prime factorization?

A product of Prime number,perhaps with some repetition, resulting in the desired amount

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 factor all numerators and denominators?

Numerators and denominators are just numbers; I hope you're not asking us to factor every number. There are many different methods. I prefer to find the prime factorization; that leads to all the other factors. Some people like to use a factor tree to help visualize the prime factorization.

What are some prime factorizations of 45?

The prime factorization of 45 is: 3 × 3 × 5 or 32 x 5

What are some prime numbers in 14?

The prime factorization of 14 is: 2 x 7 The prime numbers that are factors of 14 are 2 abd 7.

What does a factorization look like?

The prime factorization of a number uses only primes. Ex: The prime factorization of 12 is not 6 x 2, and not 4 x 3, because 6 and 4 are not prime numbers. The prime factorization is 2 x 2 x 3. Their product is 12 and all factors are prime numbers. To get a prime factorization you are usually taught to factor through division by small prime numbers, sometimes you must use the same number more than once as in the example of 12 above 2 was used twice. Ex: find the prime factorization of 18. The smallest prime is 2... divide by 2 18 / 2 = 9 .... for the next step divide 9 by a prime 9 / 3 = 3 ... this is a prme ... it is also a factor so the prime factorization is 18 = 2x3x3 Ex. find the prime factorization of 35. 35 cannot be divided by 2, or 3, so use 5 first 35 / 5 = 7 .... since 7 is a prime we are finished. The prime factorization of 35 is 35 = 5 x 7 Some teachers teach this using a "factor tree" .. I can't type one of those on a computer.

What are some prime numbers in 27?

The prime factorization of 27 is: 3 x 9 3 x 3 x 3 The prime number that is a factor of 27 is 3.

Where can I get prime factorization worksheets?

Math aids has a site to print sheets to help find and understand prime factorization. You can select a level from easy to hard for anyone that is just beginning or may already have some sort of knowledge on the subject.

What are some prime numbers in 12?

The prime factorization of 12 is: 2 x 6 2 x 2 x 3. The prime numbers that are factors of 12 are 2 and 3.

Why the is longest factor string for any whole number is the prime factorization?

Because if all the factors are prime, the factorization can't be broken down further. Consider some factor strings for 210: 2 x 105 2 x 3 x 35 2 x 3 x 5 x 7 The last (and longest) is the prime factorization.

What are the factors and prime factors of 79?

79 is a prime number. The only two factors of a prime number are 1 and itself.The only prime factor of 79 is 79. There is only one prime factor of a prime number - itself.The distinct prime factor (listing each prime factor only once) of 79 is also 79.The prime factorization of 79 is 79. In some cases, to emphasize that it is prime, you might write the prime factorization as 1 x 79.

What are some prime factorization of 80?

2 x 2 x 2 x 2 x 5 = 80

What are some rules of prime factorization?

Prime factorization is where you take a number like 24 and make it into the prime numbers that multuply to make it. like this 24 / \ 4 6 / \ / \ 2 2 2 3 The prime factorization of 24 is 2 x 2 x 2 x 3, or 2 cubed times 3. All you have to do is make the factor tree and think of two numbers that, multuplied, make the number before it until it's all prime numbers like I did.

What does the prime factorization mean?

Prime factorization is to write a multiplication problem like 6 times 2 in its simplest form with all prime numbers. so 6 is composite 3 times 2 is six so then it would be 3 times 2 times 2 and it would still give you the some answer of 12 A prime factorization is when you have a number and find the two numbers that can be multiplied together to make the number and reduce the number and ya. Here is an example: 20 is your #. Your prime factorization would be 2x2x5 because if u multiply those numbers you will get 20. There now you should know.

How do you get the answer for prime factorization?

It's done by dividing your target number by prime numbers until all the factors are prime. Some people use factor trees, rainbows, ladders, fireworks, etc. as visual aids. Example 210: 210 105,2 35,3,2 7,5,3,2 The prime factorization of 210 is 2 x 3 x 5 x 7.

Who ave the method of finding out prime numbers?

Nobody. That is because there is no pattern to prime numbers. There are various methods to find some classes of prime numbers but none that will find all of them.
