What are prime factorization trees?
What are prime factorization trees?
A factor tree shows the prime factors of a composite number in a “tree-like” form. Drawing factor trees is a good way of doing prime factorization. You can make different factor trees to find the same prime factorization. and both give the same prime factorization.
How do you use factor trees to find the prime factorization?
We will be able to find factorization by factor tree methodFinally, we get prime factors by factor tree method. Prime factorization method is the method when dividing the given number by the first prime number which is $2$ and continuing dividing by $2$ until we get a decimal or remainder. Then divide by $2,3,5,7,11$….
How do you find the factors of 72?
Here we can see all the Positive pair factors of 72.
- x 72= 72. therefore, 1 and 72 are a factor pair of 72.

How do prime factor trees work?
Factor trees are a way of expressing the factors of a number, specifically the prime factorization of a number. Each branch in the tree is split into factors. Once the factor at the end of the branch is a prime number, the only two factors are itself and one so the branch stops and we circle the number.
How do you use a factor tree?
Find a pair of factors. Pick any pair of factors for the number you’re working with. To qualify as a pair of factors, the product of the two numbers must equal your original number when multiplied together. These factors will form the first branches of your factor tree. You can pick any two factors.
What is the easiest way to find factors?
The quickest way to find the factors of a number is to divide it by the smallest prime number (bigger than 1) that goes into it evenly with no remainder. Continue this process with each number you get, until you reach 1.
How do you find the factors of a number?
How to Find Factors of a Number?
- Find all the numbers less than or equal to the given number.
- Divide the given number by each of the numbers.
- The divisors that give the remainder to be 0 are the factors of the number.
What is the 72 times table?

Which shows the prime factors for 72?
The result 3 cannot be divided any further as it is a prime number. Hence the prime factors of 72 are 2, 2, 2, 3, 3.
What are the factors of 64 and 72?
The factors of 64 (all the whole numbers that can divide the number without a remainder) are 1, 2, 4, 8, 16, 32 and 64; The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36 and 72.
How do you calculate the prime factorization of a number?
The prime factors of a number are all the prime numbers that, when multiplied together, equal the original number. You can find the prime factorization of a number by using a factor tree and dividing the number into smaller parts. You can begin by finding a prime number and factoring out that number, then continuing on in that manner.
