# Factors of 176: Prime Factorization, Methods, Tree, and Examples

**Factors**can be explained as the numbers that areÂ

**multiplied**together to give a specific number. In simple words, it can also be explained as when a given number is

**divided**by another number and it gives

**zero**as the remainder, then it is called the factor of the given number. Every number has both

**positive factors**and

**negative factors**. We can exclude the negative factors as they are not commonly used.

The number 176 has a total of**20 factors**, out of which only 10 are positive.

## What Are the Factors of 176?

**The factors of 176 are 1, 2, 4, 8, 11, 16, 22, 44, 88, and 176 as they evenly divide the number 176 with zero remainders.**

**176 is an even number**. Any whole number that divides 176 to give 0 as a remainder will be listed as a factor of 176. So, by dividing the number 176 and checking their divisibility we can form the factors list of 176. The list of Factors of 176 can be written in this form: Factors of 176 = 1, 2, 4, 8, 11, 16, 22, 44, 88, 176

## How To Calculate the Factors of 176?

You can find the factors of 176 by**multiplying**the two numbers in pairs which produces 176 as the result.Â The factors of 176 by pair

**multiplication**are given as:

**176 x 1 = 176Â **

**1 x 176 = 176Â **

**2 x 88 = 176Â **

**88 x 2 = 176Â **

**4 x 44 = 176**

**44 x 4 = 176Â **

**8 x 22 = 176Â **

**22 x 8 = 176Â **

**11 x 16 = 176Â **

**16 x 11 = 176Â **

**1, 2, 4, 8, 11, 16, 22, 44, 88,**and

**176**are the factors of 176. Another method that can be used to find the factors of 176 is the

**division method**that helps to find the natural number that is exactly divisible by 176 without leaving the remainders. You should start by dividing the number

**176**by the smallest natural number which is 1.

\[ \dfrac{176}{1} = 176\]Â

This is the main method to find the factors of 176. Now, divide 176 by 2.\[ \dfrac{176}{2} = 88Â \] Â Â Â

Again, the**remainder**is 0, which means that 2 is also the factor of 176. Now check the divisibility of 4.

\[ \dfrac{176}{4} = 44Â \] Â

Therefore, 4 is also the factor of 176. Repeat the same procedure for all the remaining numbers such that the remainder obtained is zero. \[ \dfrac{176}{8} = 22Â \] Â \[ \dfrac{176}{11} = 16Â \] Â \[ \dfrac{176}{16} = 11Â \] Â \[ \dfrac{176}{22} = 8Â \] Â \[ \dfrac{176}{44} = 4Â \] Â \[ \dfrac{176}{88} = 2 \] Â \[ \dfrac{176}{176} = 1Â \] Â Therefore, all the above-mentioned numbers are the**factors of number 176.**

## Factors of 176 by Prime Factorization

To find out if a number is evenly**divisible**by primes, you can try dividing it and seeing what the remainder is. If there’s no leftover then that would be an indication of prime numbers being the factors of the given number. This technique is called

**Prime Factorization**.

**Prime factors**of 176 are all those numbers that can only be divided by 1 and that number itself. Hence these factors, when multiplied answer 176. To find the prime factors you can follow the steps given below. Choose the smallest prime number factor i.e 2. Divide 176 by 2Â

\[ \dfrac{176}{2} = 88Â \]Â

Now divide the answer with the number 2Â\[ \dfrac{88}{2} = 44Â \]

We will keep on dividing the answer until we get a remainder in the answer\[ \dfrac{44}{2} = 22Â \]

Then:\[ \dfrac{22}{2} = 11Â \]

Since the answer is not further divisible by 2 without giving a remainder we will shift to the next prime number and will keep on repeating the steps until we get**1**in the answer.

**11/11 = 1Â Â **

**2 x 2 x 2 x 2 x 11 = 176Â **

## Factor Tree of 176

A**factor tree**is the pictorial description of the prime factorization of the given number. We can make a

**factor tree**to understand the prime factorization even more. For that, we must clarify our prime factors concept. In total, we have 5 prime factors of 176 which are 2,2,2,2 and 11. Figure 1 given below is called a factor tree.

## Factors of 176 in Pairs

A factor pair is the product of two numbers that gives that certain number. For the number 176 we will find factor pairs by multiplying any two factors to give 176 as answer. For positive factors we can find pairs in this way:**1 x 176 = 176Â **

**2 x 88 = 176Â **

**4 x 44 = 176Â **

**8 x 22 = 176Â **

**11 x 16 = 176Â **

**16 x 11 = 176Â **

**22 x 8 = 176Â **

**44 x 4 = 176Â **

**88 x 2 = 176**

**176 x 1 = 176Â **

**-1 x -176 = 176Â **

**-2 x -88 = 176Â **

**-4 x -44 = 176Â **

**-8 x -22 = 176Â **

**-11 x -16 = 176Â **

**-16 x -11 = 176Â **

**-22 x -8 = 176Â **

**-44 x -4 = 176Â **

**-88 x -2 = 176Â **

**-176 x -1 = 176Â **

So, we can write the pairs in this way to summarize the factor pairs of 176:

Positive Factor pairs of 176 are**(1, 176), (2, 88), (4, 44), (8, 22),**and

**(11, 16).**Negative Factor pairs of 176 are

**(-1, -176), (-2, -88), (-4, -44), (-8, -22),**and

**(-11, -16).**
