### Example: Find factors of 255 in pair

Factor Pair Pair Factorization
1 and 255 1 x 255 = 255
3 and 85 3 x 85 = 255
5 and 51 5 x 51 = 255
15 and 17 15 x 17 = 255

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 255. They are called negative pair factors.

Hence, the negative pairs of 255 would be ( -1 , -255 ) .

#### Definition of factor pairs?

In mathematics, factor pair are often given as pair of numbers which when multiplied together give the original number. Every natural number is a product of atleast one factor pair. Eg- Factors of 255 are 1 , 3 , 5 , 15 , 17 , 51 , 85 , 255. So, factors of 255 in pair are (1,255), (3,85), (5,51), (15,17).

#### What are factors?

In mathematics, a factor is that number which divides into another number exactly, without leaving a remainder. A factor of a number can be positive or negative.

#### Properties of Factors

• Every number is a factor of zero (0), since 255 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, 3, 5, 15, 17, 51, 85, 255 are exact divisors of 255.
• Factors of 255 are 1, 3, 5, 15, 17, 51, 85, 255. Each factor divides 255 without leaving a remainder.

#### Steps to find Factors of 255

• Step 1. Find all the numbers that would divide 255 without leaving any remainder. Starting with the number 1 upto 127 (half of 255). The number 1 and the number itself are always factors of the given number.
255 ÷ 1 : Remainder = 0
255 ÷ 3 : Remainder = 0
255 ÷ 5 : Remainder = 0
255 ÷ 15 : Remainder = 0
255 ÷ 17 : Remainder = 0
255 ÷ 51 : Remainder = 0
255 ÷ 85 : Remainder = 0
255 ÷ 255 : Remainder = 0

Hence, Factors of 255 are 1, 3, 5, 15, 17, 51, 85, and 255

• Is 255 a composite number?

Yes 255 is a composite number.

• Is 255 a perfect square?

No 255 is not a perfect square.

• Write all odd factors of 255?

The factors of 255 are 1, 3, 5, 15, 17, 51, 85, 255.
Odd factors of 255 are 1 , 3 , 5 , 15 , 17 , 51 , 85 , 255.

• What is the mean of all prime factors of 255?

Factors of 255 are 1 , 3 , 5 , 15 , 17 , 51 , 85 , 255. Prime factors of 255 are 3 , 5 , 17. Therefore mean of prime factors of 255 is (3 + 5 + 17) / 3 = 8.33.

• What do you mean by proper divisors?

A number x is said to be the proper divisor of y if it divides y completely, given that x is smaller than y.

#### Examples of Factors

How many total number of factors of 255 in pair are possible?

Factors of 255 are 1, 3, 5, 15, 17, 51, 85, 255. Hence, the factors of 255 in pair are (1,255), (3,85), (5,51), (15,17). Therefore, in total 4 pairs of factors are possible.
