You can input a number and find the prime factor, factor and factor pair.

### Prime Factorization: 2 * 2 * 3

### Factors: 1, 2, 3, 4, 6, 12

### Factor Pairs : (1,12),(2,6),(3,4)

## What is Prime Factorization?

### Prime factorization is the method for finding prime factors of a composite number. There is a theorem that states: Any integer greater than one can be uniquely written as product of prime numbers.

### Prime factor example

#### Let's take 6. It can be written as 2 x 3 which is nothing but the multiplication of two prime numbers.

find the prime factorization for 124. 124 = 2 * 2 * 31 , Here all the three factors are prime and the prime factorization of 124 is 2^{2}x 31

## How to Factorize a number?

Step 1:

As we discussed about integers, we clearly notice that all integers can be written as Multiplication of two numbers. Even we can write prime number in this way.(1 x prime.no).

Step 2:

Lets take a number xy.Try to write in multiplication of two numbers. (i.e) x * y.

Step 3:

Next is to check whether the number x and y can be written as multiplication of two numbers.We need to repeat this step until the number reaches to prime number.

### Factorization of 36

**Step 1:**Express it as multiplication of two number. 36 = 12 x 3**Step 2:**We can write 12 as multiplication of two numbers, 12 = 4 x 3 , 12 = 6 x 2.**Step 3:**4 and 6 can be written as 2 x 2 and 2 x 3 respectively.

Now collect the numbers and we can ignore the duplicate numbers. So now the factors of 12 are**2, 3, 4, 6**

## Factor Tree

### What is Factor tree?

#### Factor tree is an another way of finding the prime factors of a given number. In this method, we split the given number into two branches and again split the numbers in the branches to two numbers. Repeat this process , until the split number is a prime.

### Factor tree of 36 is 2x2 x 3x3

First we split 36 into 9 x 4. And in each branch we have composite so our aim is to split all branch element to multiples of prime numbers.So split 9 as 3 x 3 and 4 as 2 x 2 respectively in the branch. Now at the end node all the numbers are prime numbers.So the factorization of 36 is 2 x 2 3 x 3.
