### Example: Find factors of 57 in pair

Factor Pair Pair Factorization
1 and 57 1 x 57 = 57
3 and 19 3 x 19 = 57

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 57. They are called negative pair factors.

Hence, the negative pairs of 57 would be ( -1 , -57 ) .

#### 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 57 are 1 , 3 , 19 , 57. So, factors of 57 in pair are (1,57), (3,19).

#### 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, 3, 19, 57 are exact divisors of 57.
• Every number other than 1 has at least two factors, namely the number itself and 1.
• Each number is a factor of itself. Eg. 57 is a factor of itself.
• 1 is a factor of every number. Eg. 1 is a factor of 57.

#### Steps to find Factors of 57

• Step 1. Find all the numbers that would divide 57 without leaving any remainder. Starting with the number 1 upto 28 (half of 57). The number 1 and the number itself are always factors of the given number.
57 ÷ 1 : Remainder = 0
57 ÷ 3 : Remainder = 0
57 ÷ 19 : Remainder = 0
57 ÷ 57 : Remainder = 0

Hence, Factors of 57 are 1, 3, 19, and 57

• Is 57 a composite number?

Yes 57 is a composite number.

• Is 57 a perfect square?

No 57 is not a perfect square.

• Write all odd factors of 57?

The factors of 57 are 1, 3, 19, 57.
Odd factors of 57 are 1 , 3 , 19 , 57.

• What is the mean of all prime factors of 57?

Factors of 57 are 1 , 3 , 19 , 57. Prime factors of 57 are 3 , 19. Therefore mean of prime factors of 57 is (3 + 19) / 2 = 11.00.

• 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.
