### Example: Find factors of 157 in pair

Factor Pair Pair Factorization
1 and 157 1 x 157 = 157

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 157. They are called negative pair factors.

Hence, the negative pairs of 157 would be ( -1 , -157 ) , .

#### 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 157 are 1 , 157. So, factors of 157 in pair are (1,157).

#### 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

• Every factor of a number is an exact divisor of that number, example 1, 157 are exact divisors of 157.
• Every number other than 1 has at least two factors, namely the number itself and 1.
• Each number is a factor of itself. Eg. 157 is a factor of itself.
• 1 is a factor of every number. Eg. 1 is a factor of 157.

#### Steps to find Factors of 157

• Step 1. Find all the numbers that would divide 157 without leaving any remainder. Starting with the number 1 upto 78 (half of 157). The number 1 and the number itself are always factors of the given number.
157 ÷ 1 : Remainder = 0
157 ÷ 157 : Remainder = 0

Hence, Factors of 157 are 1 and 157

• Is there any even prime factor of 157?

No there is no even prime factor, i.e. 2, of 157.

• What is the mean of all prime factors of 157?

Factors of 157 are 1 , 157. Prime factors of 157 are 157. Therefore mean of prime factors of 157 is (157) / 1 = 157.00.

• What is the mean of factors of 157?

Factors of 157 are 1 , 157. therefore mean of factors of 157 is (1 + 157) / 2 = 79.00.

• 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.
