### Example: Find factors of 445 in pair

Factor Pair Pair Factorization
1 and 445 1 x 445 = 445
5 and 89 5 x 89 = 445

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 445. They are called negative pair factors.

Hence, the negative pairs of 445 would be ( -1 , -445 ) .

#### 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 445 are 1 , 5 , 89 , 445. So, factors of 445 in pair are (1,445), (5,89).

#### 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 factor of a number is an exact divisor of that number, example 1, 5, 89, 445 are exact divisors of 445.
• Every number other than 1 has at least two factors, namely the number itself and 1.
• Each number is a factor of itself. Eg. 445 is a factor of itself.
• 1 is a factor of every number. Eg. 1 is a factor of 445.

#### Steps to find Factors of 445

• Step 1. Find all the numbers that would divide 445 without leaving any remainder. Starting with the number 1 upto 222 (half of 445). The number 1 and the number itself are always factors of the given number.
445 ÷ 1 : Remainder = 0
445 ÷ 5 : Remainder = 0
445 ÷ 89 : Remainder = 0
445 ÷ 445 : Remainder = 0

Hence, Factors of 445 are 1, 5, 89, and 445

• Is there any even prime factor of 445?

No there is no even prime factor, i.e. 2, of 445.

• What is the mean of all prime factors of 445?

Factors of 445 are 1 , 5 , 89 , 445. Prime factors of 445 are 5 , 89. Therefore mean of prime factors of 445 is (5 + 89) / 2 = 47.00.

• What is the mean of factors of 445?

Factors of 445 are 1 , 5 , 89 , 445. therefore mean of factors of 445 is (1 + 5 + 89 + 445) / 4 = 135.00.

• 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.
