### Example: Find factors of 197

• Divide 197 by 1: 197 ÷ 1 : Remainder = 0
• Divide 197 by 197: 197 ÷ 197 : Remainder = 0

Hence, Factors of 197 are 1 and 197

#### 2. Steps to find factors of 197 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 197 using the division method, follow these steps:

• Step 1. Start dividing 197 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 197, which is 197. Divide 197 by 197 to obtain the quotient (1).
197 ÷ 197 = 1
• Step 3. Repeat step 1 with the obtained quotient (1).

So, the prime factorization of 197 is, 197 = 197.

#### Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 197 as shown below:

So, the prime factorization of 197 is, 197 = 197.

#### 3. Find factors of 197 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 197 would be the two numbers which, when multiplied, give 197 as the result.

The following table represents the calculation of factors of 197 in pairs:

Factor Pair Pair Factorization
1 and 197 1 x 197 = 197

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 197. They are called negative pair factors.

Hence, the negative pairs of 197 would be ( -1 , -197 ) , .

#### How do you explain factors?

In mathematics, a factor is a number or also it can be an algebraic expression that divides another number or any expression completely and that too without leaving any remainder. A factor of a number can be positive or negative.

#### Properties of factors
