### Example: Find factors of 425 in pair

Factor Pair Pair Factorization
1 and 425 1 x 425 = 425
5 and 85 5 x 85 = 425
17 and 25 17 x 25 = 425

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 425. They are called negative pair factors.

Hence, the negative pairs of 425 would be ( -1 , -425 ) .

#### 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 425 are 1 , 5 , 17 , 25 , 85 , 425. So, factors of 425 in pair are (1,425), (5,85), (17,25).

#### 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, 17, 25, 85, 425 are exact divisors of 425.
• Every number other than 1 has at least two factors, namely the number itself and 1.
• Each number is a factor of itself. Eg. 425 is a factor of itself.
• 1 is a factor of every number. Eg. 1 is a factor of 425.

#### Steps to find Factors of 425

• Step 1. Find all the numbers that would divide 425 without leaving any remainder. Starting with the number 1 upto 212 (half of 425). The number 1 and the number itself are always factors of the given number.
425 ÷ 1 : Remainder = 0
425 ÷ 5 : Remainder = 0
425 ÷ 17 : Remainder = 0
425 ÷ 25 : Remainder = 0
425 ÷ 85 : Remainder = 0
425 ÷ 425 : Remainder = 0

Hence, Factors of 425 are 1, 5, 17, 25, 85, and 425

• Is 425 a perfect square?

No 425 is not a perfect square.

• Write five multiples of 425.

Five multiples of 425 are 850, 1275, 1700, 2125, 2550.

• Is there any even prime factor of 425?

No there is no even prime factor, i.e. 2, of 425.

• 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.
