### Example: Find factors of 220 in pair

Factor Pair Pair Factorization
1 and 220 1 x 220 = 220
2 and 110 2 x 110 = 220
4 and 55 4 x 55 = 220
5 and 44 5 x 44 = 220
10 and 22 10 x 22 = 220
11 and 20 11 x 20 = 220

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 220. They are called negative pair factors.

Hence, the negative pairs of 220 would be ( -1 , -220 ) .

#### 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 220 are 1 , 2 , 4 , 5 , 10 , 11 , 20 , 22 , 44 , 55 , 110 , 220. So, factors of 220 in pair are (1,220), (2,110), (4,55), (5,44), (10,22), (11,20).

#### 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

• Each number is a factor of itself. Eg. 220 is a factor of itself.
• 1 is a factor of every number. Eg. 1 is a factor of 220.
• Every number is a factor of zero (0), since 220 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, 5, 10, 11, 20, 22, 44, 55, 110, 220 are exact divisors of 220.
• Factors of 220 are 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220. Each factor divides 220 without leaving a remainder.
• Every factor of a number is less than or equal to the number, eg. 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220 are all less than or equal to 220.

#### Steps to find Factors of 220

• Step 1. Find all the numbers that would divide 220 without leaving any remainder. Starting with the number 1 upto 110 (half of 220). The number 1 and the number itself are always factors of the given number.
220 ÷ 1 : Remainder = 0
220 ÷ 2 : Remainder = 0
220 ÷ 4 : Remainder = 0
220 ÷ 5 : Remainder = 0
220 ÷ 10 : Remainder = 0
220 ÷ 11 : Remainder = 0
220 ÷ 20 : Remainder = 0
220 ÷ 22 : Remainder = 0
220 ÷ 44 : Remainder = 0
220 ÷ 55 : Remainder = 0
220 ÷ 110 : Remainder = 0
220 ÷ 220 : Remainder = 0

Hence, Factors of 220 are 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, and 220

• Is 220 a composite number?

• Write five multiples of 220.

Five multiples of 220 are 440, 660, 880, 1100, 1320.

• Write all odd factors of 220?

The factors of 220 are 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220.
Odd factors of 220 are 1 , 5 , 11 , 55.

• What is the mean of all prime factors of 220?

Factors of 220 are 1 , 2 , 4 , 5 , 10 , 11 , 20 , 22 , 44 , 55 , 110 , 220. Prime factors of 220 are 2 , 2 , 5 , 11. Therefore mean of prime factors of 220 is (2 + 2 + 5 + 11) / 4 = 5.00.
