### Example: Find factors of 19 in pair

Factor Pair Pair Factorization
1 and 19 1 x 19 = 19

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 19. They are called negative pair factors.

Hence, the negative pairs of 19 would be ( -1 , -19 ) , .

#### What does factor pairs of a number mean?

Factor pairs are those factors in pair that can give original number when multiplied. Every natural number is a product of atleast one factor pair. Eg- Factors of 19 are 1 , 19. So, factors of 19 in pair are (1,19).

#### How can we define factors?

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

#### Properties of Factors

• Every number is a factor of zero (0), since 19 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, 19 are exact divisors of 19.
• Factors of 19 are 1, 19. Each factor divides 19 without leaving a remainder.

#### Steps to find Factors of 19

• Step 1. Find all the numbers that would divide 19 without leaving any remainder. Starting with the number 1 upto 9 (half of 19). The number 1 and the number itself are always factors of the given number.
19 ÷ 1 : Remainder = 0
19 ÷ 19 : Remainder = 0

Hence, Factors of 19 are 1 and 19

• Is there any even prime factor of 19?

No there is no even prime factor, i.e. 2, of 19.

• What is the mean of all prime factors of 19?

Factors of 19 are 1 , 19. Prime factors of 19 are 19. Therefore mean of prime factors of 19 is (19) / 1 = 19.00.

• What is the mean of factors of 19?

Factors of 19 are 1 , 19. therefore mean of factors of 19 is (1 + 19) / 2 = 10.00.

• 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.
