**Factors of 160: Prime Factorization, Methods, Tree, and Examples**

**Factors of 160** are numbers that may completely divide 160 or produce 160 when two values are multiplied together. An integer divides 160 by itself with a remainder of 0. Hence it is considered to be a factor if it does so.

The** factors of the number 160**, as well as factor pairs, factor tree, simple solutions, and much more, are all covered in this article. Simply said, finding the factors of any number will be a piece of cake for you after going through this article.

**What Are the Factors of 160?**

**Factors of 160 are as follows: ****1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80 and 160.** As it is a **composite number**, 160 has more than two factors. In total, **160 have twelve factors.**

The numbers that divide 160 perfectly without giving a remainder are known as its factors. The factors can also be written in the form of factor pairs. For example, one of the factor pairs is (1, 160).

**How To Calculate the Factors of 160?**

To **Calculate the factors of 160**, the following are the two main processes:

**Division**

**Multiplication**

To find out if they have any **factors**, come up with a list of all the numbers that are less than or equal to the one you are looking for. Next, look over the list. For 160, the possible values will range from 1 to 80.

Then, by **dividing** each of them, one can obtain the answer. You can discover a numberâ€™s factor in two different ways: either by division or multiplication.

But even so, many methods exist for determining an integerâ€™s factors. Once the **remainder equals zero**, you divide the original number by itself and consider the quotient and divisor factors of the provided number. As an example, letâ€™s look at one of these situations.

32 is the result of 160 divided by 5. As a result, the divisor, as well as the solution, are considered factors. They are referred to collectively as factor pairs. (5, 32)

Letâ€™s first discuss the **method of division** in detail. Find any numbers that are less than or equal to 160 by making a list. Each number should then be multiplied by 160. The remainder of 160 after dividing by its factors is 0.

To further grasp this concept, look at the example below:

Other than 1, the smallest factor of 160 is 2, so we **divide 160** by 2 to get 80. Consequently, the factors of 160 are 2 and 80.

\[ \frac{160}{2} = 80 \]

Here is a list of all the factors of 160 in ascending order:

\[ \frac{160}{1} = 160 \]

\[ \frac{160}{2} = 80 \]

\[ \frac{160}{4} = 40 \]

\[ \frac{160}{5} = 32 \]

\[ \frac{160}{8} = 20 \]

\[ \frac{160}{10} = 16 \]

\[ \frac{160}{16} = 10 \]

\[ \frac{160}{20} = 8 \]

\[ \frac{160}{32} = 5 \]

\[ \frac{160}{40} = 4 \]

\[ \frac{160}{80} = 2 \]

\[ \frac{160}{160} = 1 \]

Therefore, the** twelve factors of 160** are 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80 and 160.

Moving on to the process of **multiplication** to determine the factors of 160. All of the numbers in each of these products are factors of 160.

**1 x 160 = 160**

**2 x 80 = 160**

**4 x 40 = 160**

**5 x 32 = 160**

**8 x 20 = 160**

**10 x 16 = 160**

Hence, factors of 160 are mentioned above.

**Factors of 160 by Prime Factorization**

**Prime Factorization **is a mathematical technique for expressing a number by a collection of factors multiplied together. It is a method for figuring out or showing a given integer as the sum of prime integers or in another manner.

Described, it is a method for identifying or presenting a given integer as the sum of **prime numbers**. The prime factorization process is as follows:

The **smallest prime number** evenly divides 160, leaving a 0 as the only remainder. After that, it is divided by the smallest or second smallest prime number again until the quotient is no longer divisible. Letâ€™s divide 160 by the prime number 2.

Â \[ \frac{160}{2} = 80 \]

As the answer is a **whole number**, 2 and 80 are the factors of 160.

We must now divide 80 by the following least prime number.

\[ \frac{80}{2} = 40 \]

Next, we divide 40 by 2, which gives us 20. Further division results in the following:

\[ \frac{20}{2} = 10 \]

\[ \frac{10}{2} = 5 \]

Since 5 is a prime number, it is impossible to divide it further. Henceforth, 2 and 5 are the prime factors of 160. The notations used to indicate the prime factors of 160 are **2 x 2 x 2 x 2 x 2 x 5.**

The diagram below shows the prime factorization of 160:

**Factor Tree of 160**

Even though a numberâ€™s factors can be represented in many different ways, one of the most common ways to graphically display a numberâ€™s prime factors is using a **Factor Tree**.

The actual number serves as the factor tree’s root, and branches extend to the prime number from this root. Thus, through prime factorization, 2 and 5 are regarded as the prime factors of 160.

Below is the diagram which shows the factor tree of 160:
