**Factors of 23 are 1, 23**.

Here is complete detailed methods to find the factors of 23.

Actually, Factor is a number which divides any number completely without leaving remainder.

Or simply we can say that if we multiply two whole numbers (positive & negative) and it gives a product. Then the numbers that we multiply, are the factors of the product.

For example, if we multiply 1 to 23, it gives 23. Here 1 and 23 are called positive factors and if we multiply -1 to -23, it gives 23. So -1 and -23 are called negative factors.

## How to Find The Factors of 23 ?

Since factors of 23 are the numbers, which divides 23 completely without leaving remainder. So here we are going to divide 23 by all numbers up to 23. Let’s see the process –

We have to stop the process, if any number of column ‘B’ appears in column ‘A’ or when any element comes in both columns at same level and this element will consider as a factor.

Here we stop the division when 23 appears in column ‘A’, which has already been came in column ‘B’.

Hence, all the factor of 23 in above table are : 1, 23

Similarly, negative factor of 23 are : -1, -23

## What Are The Factors of 23 in Pairs ?

As we saw in above table, 1 multiply by 23 gives 23. So (1, 23) is a factor pair of 23. Let us see how many factor pairs can be achieved –

1 x 23 = 23

23 x 1 = 23

Similarly, negative factor pairs of 23 can be written as follows –

-1 x -23 = 23

-23 x -1 = 23

Hence, 23 has 2 factor pairs.

## What Are the Prime Factors of 23 ?

Since 23 is itself a prime number, hence it has only one prime factor i.e. 23. Here we will discuss, mainly two methods of factorization to find Prime Factors of any number.

- Division Method
- Factor Tree Method

### Prime Factors of 23 by Division Method

**Step 1 :** Divide the number by the smallest prime number, which divides the number exactly.**Step 2 :** Divide the quotient again by the smallest prime number. If quotient is not exactly divisible by the

smallest prime number, choose next smallest prime number.**Step 3 :** Repeat Step 2 again and again till the quotient becomes 1.**Step 4 :** All the prime numbers used in above process are the prime factors.

Check : Multiply all the prime factors, the multiplication should be the number itself.

Caution : In this method, only prime numbers will be use to divide.

Since 23 is a prime number, hence 23 has only one prime factor i.e. 23.

### Factor Tree of 23

**Step 1 :** Write a number as root of the tree**Step 2 :** Find the factors of the number, each factor will be considered as root again (now, we got 2 new root)**Step 3 :** Repeat step 2 until we can’t factor any more (or until we got prime factor)**Step 4 :** The end nodes are the prime factors.

We can initiate the tree by choosing any two factors. Here we choose 1 and 23 as factors of 23.

We got the same unique nodes in every tree.

The Factor Tree may be made so many types depends upon choosing the initial and middle factors.

## Number of Factors of 23

The **Number of Factors of 23 is **2.

If we consider both positive and negative factors, then

total no. of factors = 2 (positive) + 2 (negative) = 4

I hope, this step-by-step tutorial will be helpful to understand factorization method of 23.
