### Example: Find factors of 369 in pair

Factor Pair Pair Factorization
1 and 369 1 x 369 = 369
3 and 123 3 x 123 = 369
9 and 41 9 x 41 = 369

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 369. They are called negative pair factors.

Hence, the negative pairs of 369 would be ( -1 , -369 ) .

#### What does factor pairs of a number mean?

Factor pairs are those factors in pair that can give original number when multiplied. Every natural number is a product of atleast one factor pair. Eg- Factors of 369 are 1 , 3 , 9 , 41 , 123 , 369. So, factors of 369 in pair are (1,369), (3,123), (9,41).

#### How can we define factors?

In mathematics, a factor is a number which divides into another number exactly, without leaving any remainder. A factor of a number can be positive of negative.

#### Properties of Factors

• Every factor of a number is an exact divisor of that number, example 1, 3, 9, 41, 123, 369 are exact divisors of 369.
• Every number other than 1 has at least two factors, namely the number itself and 1.
• Each number is a factor of itself. Eg. 369 is a factor of itself.
• 1 is a factor of every number. Eg. 1 is a factor of 369.

#### Steps to find Factors of 369

• Step 1. Find all the numbers that would divide 369 without leaving any remainder. Starting with the number 1 upto 184 (half of 369). The number 1 and the number itself are always factors of the given number.
369 ÷ 1 : Remainder = 0
369 ÷ 3 : Remainder = 0
369 ÷ 9 : Remainder = 0
369 ÷ 41 : Remainder = 0
369 ÷ 123 : Remainder = 0
369 ÷ 369 : Remainder = 0

Hence, Factors of 369 are 1, 3, 9, 41, 123, and 369

• Is 369 a composite number?

Yes 369 is a composite number.

• Is 369 a perfect square?

No 369 is not a perfect square.

• Write all odd factors of 369?

The factors of 369 are 1, 3, 9, 41, 123, 369.
Odd factors of 369 are 1 , 3 , 9 , 41 , 123 , 369.

• What is the mean of all prime factors of 369?

Factors of 369 are 1 , 3 , 9 , 41 , 123 , 369. Prime factors of 369 are 3 , 3 , 41. Therefore mean of prime factors of 369 is (3 + 3 + 41) / 3 = 15.67.

• 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.
