#### 2. Steps to find factors of 812 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 812 using the division method, follow these steps:

• Step 1. Start dividing 812 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 812, which is 2. Divide 812 by 2 to obtain the quotient (406).
812 ÷ 2 = 406
• Step 3. Repeat step 1 with the obtained quotient (406).
406 ÷ 2 = 203
203 ÷ 7 = 29
29 ÷ 29 = 1

So, the prime factorization of 812 is, 812 = 2 x 2 x 7 x 29.

#### Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 812 as shown below:

So, the prime factorization of 812 is, 812 = 2 x 2 x 7 x 29.

#### 3. Find factors of 812 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 812 would be the two numbers which, when multiplied, give 812 as the result.

The following table represents the calculation of factors of 812 in pairs:

Factor Pair Pair Factorization
1 and 812 1 x 812 = 812
2 and 406 2 x 406 = 812
4 and 203 4 x 203 = 812
7 and 116 7 x 116 = 812
14 and 58 14 x 58 = 812
28 and 29 28 x 29 = 812

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 812. They are called negative pair factors.

Hence, the negative pairs of 812 would be ( -1 , -812 ) , ( -2 , -406 ) , ( -4 , -203 ) , ( -7 , -116 ) , ( -14 , -58 ) and ( -28 , -29 ) .

#### 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

• Each number is a factor of itself. Eg. 812 is a factor of itself.
• 1 is a factor of every number. Eg. 1 is a factor of 812.
• Every number is a factor of zero (0), since 812 x 0 = 0.
• Every number other than 1 has at least two factors, namely the number itself and 1.
• Every factor of a number is an exact divisor of that number, example 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812 are exact divisors of 812.
• Factors of 812 are 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812. Each factor divides 812 without leaving a remainder.
• Every factor of a number is less than or equal to the number, eg. 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812 are all less than or equal to 812.
