All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor tree can help you visualize this.
Example: 210
210 Divide by two.
105,2 Divide by three.
35,3,2 Divide by five.
7,5,3,2 Stop. All the factors are prime.
2 x 3 x 5 x 7 = 210
That's the prime factorization of 210.
What else can I help you with?
How can making a factor tree help you find the prime factorization of a number?
If completed correctly, the bottom branch of a factor tree will be the prime factorization of the number at the top.
Write the prime factorization of 10 and of 100 then look for a pattern to help you find the prime factorization of 1000?
The prime factorization of 10 is 2 x 5. The prime factorization of 100 is 2^2 x 5^2. The prime factorization of 1000 is 2^3 x 5^3.
What is the use of prime factorization?
Prime factorization helps to find the greatest common factor and the least common multiple which, in turn, help in the adding, subtracting and reducing of fractions.
How do you find the greatest prime factor by using prime factorization?
Prime factorization is a way to express every composite number as the product of prime numbers(or prime factors). Let us consider the number 100. Prime factorization of 100 = 2 x 2 x 5 x 5. It can be seen that there are two distinct prime factors: 2 and 5. And 5 is the greatest prime factor. 100 can be expressed as 2 x 50. The only prime factor we have in this expression is 2 and this makes us to think that 2 is the only prime factor of 100, which is untrue. So with the help of prime factorization it is possible to find all the prime factors and the greatest prime factor.
What is the prime factorization and the greatest common factor of 2456?
The prime factorization of 2456 is 2 x 2 x 2 x 307. There is not a greatest common factor. To have a greatest common factor, you need two or more numbers. A common factor is a factor that two or more number have in common. However, the prime factorization of all the numbers will help you find the greatest common factor. The greatest common factor will be the prime factors they have in common multiplied together. Examples: The prime factorization of 36 is 2 x 2 x 3 x 3. The prime factors it has in common with 2456 are 2 and 2, so the greatest common factor is 2 x 2 = 4. The prime factorization of 921 is 3 x 307. The prime factors that it has in common with 2456 is 307, so the greatest common factor is 307.
How do you find the greatest common factor of 30135 using prime factorization?
You do not. To have a greatest common factor, you need two or more numbers. A common factor is a factor that two or more number have in common. However, the prime factorization of all the numbers will help you find the greatest common factor. The greatest common factor will be the prime factors they have in common multiplied together. Example: The prime factorization of 30135 is 3 x 5 x 7 x 7 x 41. The prime factorization of 98 is 2 x 7 x 7. The prime factors they have in common are 7 and 7, so the greatest common factor is 7 x 7 = 49.
How does a factor tree help?
It's a way of visualizing and notating the process of finding the prime factorization of a given composite number. Some people can do it in their heads, but for most of us, it's easier to write it down.
How do you get a prime factor?
All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor tree can help you visualize this.Example: 210210 Divide by two.105,2 Divide by three.35,3,2 Divide by five.7,5,3,2 Stop. All the factors are prime.2 x 3 x 5 x 7 = 210That's the prime factorization of 210.
How do you use a factor tree to write the prime factorization?

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.
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.
How do you find the greatest common factor of 45 using prime factorization?
You do not. To have a greatest common factor, you need two or more numbers. A common factor is a factor that two or more number have in common. However, the prime factorization of all the numbers will help you find the greatest common factor. The greatest common factor will be the prime factors they have in common multiplied together. Example: The prime factors of 45 are 3, 3, and 5. The prime factors of 60 are 2, 2, 3, and 5. The common prime factors are 3 and 5, so the greatest common factor is 3 x 5 = 15.
