#### 2. Steps to find factors of 512 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 512 using the division method, follow these steps:

• Step 1. Start dividing 512 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 512, which is 2. Divide 512 by 2 to obtain the quotient (256).
512 ÷ 2 = 256
• Step 3. Repeat step 1 with the obtained quotient (256).
256 ÷ 2 = 128
128 ÷ 2 = 64
64 ÷ 2 = 32
32 ÷ 2 = 16
16 ÷ 2 = 8
8 ÷ 2 = 4
4 ÷ 2 = 2
2 ÷ 2 = 1

So, the prime factorization of 512 is, 512 = 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2.

#### Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 512 as shown below:

So, the prime factorization of 512 is, 512 = 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2.

#### 3. Find factors of 512 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 512 would be the two numbers which, when multiplied, give 512 as the result.

The following table represents the calculation of factors of 512 in pairs:

Factor Pair Pair Factorization
1 and 512 1 x 512 = 512
2 and 256 2 x 256 = 512
4 and 128 4 x 128 = 512
8 and 64 8 x 64 = 512
16 and 32 16 x 32 = 512

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 512. They are called negative pair factors.

Hence, the negative pairs of 512 would be ( -1 , -512 ) , ( -2 , -256 ) , ( -4 , -128 ) , ( -8 , -64 ) and ( -16 , -32 ) .

#### 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. 512 is a factor of itself.
• 1 is a factor of every number. Eg. 1 is a factor of 512.
• Every number is a factor of zero (0), since 512 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, 8, 16, 32, 64, 128, 256, 512 are exact divisors of 512.
• Factors of 512 are 1, 2, 4, 8, 16, 32, 64, 128, 256, 512. Each factor divides 512 without leaving a remainder.
• Every factor of a number is less than or equal to the number, eg. 1, 2, 4, 8, 16, 32, 64, 128, 256, 512 are all less than or equal to 512.
