Write the composite number you want to factor on a piece of paper.
Write one of its factor pairs underneath it.
If possible, keep breaking each factor down until all the factors are prime.
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.
When the bottom branch consists entirely of prime numbers.
Not really. A factor string is a multiplication sentence. A factor tree is a way of notating the process of finding the prime factorization of a given number. End result: 4 x 9 can be a factor string for 36, but can't be a prime factorization. The prime factorization of 36 is 2 x 2 x 3 x 3.
No if you put honey on the tree then with luck (lucky egg) you will encounter munchlax eventualy.
Notice whether the number is odd or even. If it's even, the first prime factor is 2.
The difference is between factor pairs and distinct factors. With square numbers, one of the factor pairs will be the same number twice. When listing the distinct factors, that number is only listed once.
No.
No.
No.
113 is a prime number. The only way to factor it would be 113 x 1.
A factor tree is a way to notate the process of finding the prime factorization. If completed successfully, the bottom row (branch) will display the prime factorization of the number you started with.
A factor tree is one way of notating the process of finding the prime factorization of a given number.
A factor tree is a way to notate the process of finding the prime factorization of a given number.
Factor trees are a way to notate the process of finding the prime factorization of a given number. Since each number has its own unique prime factorization, each has its own single factor tree.
When the bottom branch consists entirely of prime numbers.
A factor tree is a way to notate the process of finding the prime factorization of a given number by writing the number at the top and breaking it down into factors on subsequent lines or "branches." The tree is complete when the bottom branch consists only of prime numbers.
A composite number has a unique prime factorization, but there can be different factor trees that lead to it depending on what factors you choose. 36 18,2 9,2,2 3,3,2,2 36 6,6 2,3,6 2,3,2,3 36 9,4 3,3,4 3,3,2,2 36 12,3 3,4,3 3,2,2,3
A factor rainbow is a way of notating the process of finding the prime factorization of a given number. It's an upside down factor tree. Example: 2107,5,3,235,3,2105,2210
