### Example: Find factors of 817

• Divide 817 by 1: 817 ÷ 1 : Remainder = 0
• Divide 817 by 19: 817 ÷ 19 : Remainder = 0
• Divide 817 by 43: 817 ÷ 43 : Remainder = 0
• Divide 817 by 817: 817 ÷ 817 : Remainder = 0

Hence, Factors of 817 are 1, 19, 43, and 817

#### 2. Steps to find factors of 817 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 817 using the division method, follow these steps:

• Step 1. Start dividing 817 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 817, which is 19. Divide 817 by 19 to obtain the quotient (43).
817 ÷ 19 = 43
• Step 3. Repeat step 1 with the obtained quotient (43).
43 ÷ 43 = 1

So, the prime factorization of 817 is, 817 = 19 x 43.

#### Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 817 as shown below:

So, the prime factorization of 817 is, 817 = 19 x 43.

#### 3. Find factors of 817 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 817 would be the two numbers which, when multiplied, give 817 as the result.

The following table represents the calculation of factors of 817 in pairs:

Factor Pair Pair Factorization
1 and 817 1 x 817 = 817
19 and 43 19 x 43 = 817

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 817. They are called negative pair factors.

Hence, the negative pairs of 817 would be ( -1 , -817 ) , ( -19 , -43 ) .

#### 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
