### Example: Find factors of 451 in pair

Factor Pair Pair Factorization
1 and 451 1 x 451 = 451
11 and 41 11 x 41 = 451

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 451. They are called negative pair factors.

Hence, the negative pairs of 451 would be ( -1 , -451 ) .

#### Introduction to factor pairs

Factor pair in mathematics is defined as all factors of a given number which when written in pair and multiplied gives the original number. Every natural number is a product of atleast one factor pair. Eg- Factors of 451 are 1 , 11 , 41 , 451. So, factors of 451 in pair are (1,451), (11,41).

#### How can we define factors?

In mathematics a factor is a number which divides into another without leaving any remainder. Or we can say, any two numbers that multiply to give a product are both factors of that product. It can be both positive or negative.

#### Properties of Factors

• Every number is a factor of zero (0), since 451 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, 11, 41, 451 are exact divisors of 451.
• Factors of 451 are 1, 11, 41, 451. Each factor divides 451 without leaving a remainder.

#### Steps to find Factors of 451

• Step 1. Find all the numbers that would divide 451 without leaving any remainder. Starting with the number 1 upto 225 (half of 451). The number 1 and the number itself are always factors of the given number.
451 ÷ 1 : Remainder = 0
451 ÷ 11 : Remainder = 0
451 ÷ 41 : Remainder = 0
451 ÷ 451 : Remainder = 0

Hence, Factors of 451 are 1, 11, 41, and 451

• Is there any even prime factor of 451?

No there is no even prime factor, i.e. 2, of 451.

• What is the mean of all prime factors of 451?

Factors of 451 are 1 , 11 , 41 , 451. Prime factors of 451 are 11 , 41. Therefore mean of prime factors of 451 is (11 + 41) / 2 = 26.00.

• What is the mean of factors of 451?

Factors of 451 are 1 , 11 , 41 , 451. therefore mean of factors of 451 is (1 + 11 + 41 + 451) / 4 = 126.00.

• 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.
