### Example: Find factors of 181

• Divide 181 by 1: 181 ÷ 1 : Remainder = 0
• Divide 181 by 181: 181 ÷ 181 : Remainder = 0

Hence, Factors of 181 are 1 and 181

#### 2. Steps to find factors of 181 using Prime Factorization

A prime number is a number that has exactly two factors, 1 and the number itself. Prime factorization of a number means breaking down of the number into the form of products of its prime factors.

There are two different methods that can be used for the prime factorization.

#### Method 1: Division Method

To find the primefactors of 181 using the division method, follow these steps:

• Step 1. Start dividing 181 by the smallest prime number, i.e., 2, 3, 5, and so on. Find the smallest prime factor of the number.
• Step 2. After finding the smallest prime factor of the number 181, which is 181. Divide 181 by 181 to obtain the quotient (1).
181 ÷ 181 = 1
• Step 3. Repeat step 1 with the obtained quotient (1).

So, the prime factorization of 181 is, 181 = 181.

#### Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 181 as shown below:

So, the prime factorization of 181 is, 181 = 181.

#### 3. Find factors of 181 in Pairs

Pair factors of a number are any two numbers which, which on multiplying together, give that number as a result. The pair factors of 181 would be the two numbers which, when multiplied, give 181 as the result.

The following table represents the calculation of factors of 181 in pairs:

Factor Pair Pair Factorization
1 and 181 1 x 181 = 181

Since the product of two negative numbers gives a positive number, the product of the negative values of both the numbers in a pair factor will also give 181. They are called negative pair factors.

Hence, the negative pairs of 181 would be ( -1 , -181 ) , .

#### How can we define factors?

In mathematics a factor is a number which divides into another without leaving any remainder. Or we can say, any two numbers that multiply to give a product are both factors of that product. It can be both positive or negative.

#### Properties of factors

• Every factor of a number is an exact divisor of that number, example 1, 181 are exact divisors of 181.
• Every number other than 1 has at least two factors, namely the number itself and 1.
• Each number is a factor of itself. Eg. 181 is a factor of itself.
• 1 is a factor of every number. Eg. 1 is a factor of 181.
