### Example: Find factors of 252 in pair

Factor Pair Pair Factorization
1 and 252 1 x 252 = 252
2 and 126 2 x 126 = 252
3 and 84 3 x 84 = 252
4 and 63 4 x 63 = 252
6 and 42 6 x 42 = 252
7 and 36 7 x 36 = 252
9 and 28 9 x 28 = 252
12 and 21 12 x 21 = 252
14 and 18 14 x 18 = 252

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 252. They are called negative pair factors.

Hence, the negative pairs of 252 would be ( -1 , -252 ) .

#### 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 252 are 1 , 2 , 3 , 4 , 6 , 7 , 9 , 12 , 14 , 18 , 21 , 28 , 36 , 42 , 63 , 84 , 126 , 252. So, factors of 252 in pair are (1,252), (2,126), (3,84), (4,63), (6,42), (7,36), (9,28), (12,21), (14,18).

#### 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. 252 is a factor of itself.
• 1 is a factor of every number. Eg. 1 is a factor of 252.
• Every number is a factor of zero (0), since 252 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, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252 are exact divisors of 252.
• Factors of 252 are 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252. Each factor divides 252 without leaving a remainder.
• Every factor of a number is less than or equal to the number, eg. 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252 are all less than or equal to 252.

#### Steps to find Factors of 252

• Step 1. Find all the numbers that would divide 252 without leaving any remainder. Starting with the number 1 upto 126 (half of 252). The number 1 and the number itself are always factors of the given number.
252 ÷ 1 : Remainder = 0
252 ÷ 2 : Remainder = 0
252 ÷ 3 : Remainder = 0
252 ÷ 4 : Remainder = 0
252 ÷ 6 : Remainder = 0
252 ÷ 7 : Remainder = 0
252 ÷ 9 : Remainder = 0
252 ÷ 12 : Remainder = 0
252 ÷ 14 : Remainder = 0
252 ÷ 18 : Remainder = 0
252 ÷ 21 : Remainder = 0
252 ÷ 28 : Remainder = 0
252 ÷ 36 : Remainder = 0
252 ÷ 42 : Remainder = 0
252 ÷ 63 : Remainder = 0
252 ÷ 84 : Remainder = 0
252 ÷ 126 : Remainder = 0
252 ÷ 252 : Remainder = 0

Hence, Factors of 252 are 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, and 252

• Is 252 a composite number?

Yes 252 is a composite number.

• Is 252 a prime number?

• What is the mean of factors of 252?

Factors of 252 are 1 , 2 , 3 , 4 , 6 , 7 , 9 , 12 , 14 , 18 , 21 , 28 , 36 , 42 , 63 , 84 , 126 , 252. therefore mean of factors of 252 is (1 + 2 + 3 + 4 + 6 + 7 + 9 + 12 + 14 + 18 + 21 + 28 + 36 + 42 + 63 + 84 + 126 + 252) / 18 = 40.44.

• 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.
