### Example: Find factors of 55 in pair

Factor Pair Pair Factorization
1 and 55 1 x 55 = 55
5 and 11 5 x 11 = 55

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 55. They are called negative pair factors.

Hence, the negative pairs of 55 would be ( -1 , -55 ) .

#### 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 55 are 1 , 5 , 11 , 55. So, factors of 55 in pair are (1,55), (5,11).

#### 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 55 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, 5, 11, 55 are exact divisors of 55.
• Factors of 55 are 1, 5, 11, 55. Each factor divides 55 without leaving a remainder.

#### Steps to find Factors of 55

• Step 1. Find all the numbers that would divide 55 without leaving any remainder. Starting with the number 1 upto 27 (half of 55). The number 1 and the number itself are always factors of the given number.
55 ÷ 1 : Remainder = 0
55 ÷ 5 : Remainder = 0
55 ÷ 11 : Remainder = 0
55 ÷ 55 : Remainder = 0

Hence, Factors of 55 are 1, 5, 11, and 55

• Is there any even prime factor of 55?

No there is no even prime factor, i.e. 2, of 55.

• What is the mean of all prime factors of 55?

Factors of 55 are 1 , 5 , 11 , 55. Prime factors of 55 are 5 , 11. Therefore mean of prime factors of 55 is (5 + 11) / 2 = 8.00.

• What is the mean of factors of 55?

Factors of 55 are 1 , 5 , 11 , 55. therefore mean of factors of 55 is (1 + 5 + 11 + 55) / 4 = 18.00.

• 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.

• What do you mean by improper divisors?

An improper divisor of a number is the number itself apart from this any divisor of a given number is a proper divisor.

#### Examples of Factors

How many total number of factors of 55 in pair are possible?

Factors of 55 are 1, 5, 11, 55. Hence, the factors of 55 in pair are (1,55), (5,11). Therefore, in total 2 pairs of factors are possible.
