### Example: Find factors of 162 in pair

Factor Pair Pair Factorization
1 and 162 1 x 162 = 162
2 and 81 2 x 81 = 162
3 and 54 3 x 54 = 162
6 and 27 6 x 27 = 162
9 and 18 9 x 18 = 162

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 162. They are called negative pair factors.

Hence, the negative pairs of 162 would be ( -1 , -162 ) .

#### How do you define factor pairs of a number?

A factor pair of a number can be defined as the combination of two factors in such a way that when multiplied together produce the number itself. Every natural number is a product of atleast one factor pair. Eg- Factors of 162 are 1 , 2 , 3 , 6 , 9 , 18 , 27 , 54 , 81 , 162. So, factors of 162 in pair are (1,162), (2,81), (3,54), (6,27), (9,18).

#### How do you explain factors?

In mathematics, a factor is a number or also it can be an algebraic expression that divides another number or any expression completely and that too without leaving any remainder. A factor of a number can be positive or negative.

#### Properties of Factors

• Each number is a factor of itself. Eg. 162 is a factor of itself.
• 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, 3, 6, 9, 18, 27, 54, 81, 162 are exact divisors of 162.
• 1 is a factor of every number. Eg. 1 is a factor of 162.
• Every number is a factor of zero (0), since 162 x 0 = 0.

#### Steps to find Factors of 162

• Step 1. Find all the numbers that would divide 162 without leaving any remainder. Starting with the number 1 upto 81 (half of 162). The number 1 and the number itself are always factors of the given number.
162 ÷ 1 : Remainder = 0
162 ÷ 2 : Remainder = 0
162 ÷ 3 : Remainder = 0
162 ÷ 6 : Remainder = 0
162 ÷ 9 : Remainder = 0
162 ÷ 18 : Remainder = 0
162 ÷ 27 : Remainder = 0
162 ÷ 54 : Remainder = 0
162 ÷ 81 : Remainder = 0
162 ÷ 162 : Remainder = 0

Hence, Factors of 162 are 1, 2, 3, 6, 9, 18, 27, 54, 81, and 162

• Is 162 a composite number?

Yes 162 is a composite number.

• Is 162 a prime number?

No 162 is not a prime number.

• What is the mean of factors of 162?

Factors of 162 are 1 , 2 , 3 , 6 , 9 , 18 , 27 , 54 , 81 , 162. therefore mean of factors of 162 is (1 + 2 + 3 + 6 + 9 + 18 + 27 + 54 + 81 + 162) / 10 = 36.30.

• 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.
