### Example: Find factors of 438 in pair

Factor Pair Pair Factorization
1 and 438 1 x 438 = 438
2 and 219 2 x 219 = 438
3 and 146 3 x 146 = 438
6 and 73 6 x 73 = 438

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 438. They are called negative pair factors.

Hence, the negative pairs of 438 would be ( -1 , -438 ) .

#### What does factor pairs in mathematics mean?

In mathematics, factor pair of a number are all those possible combination which when multiplied together give the original number in return. Every natural number is a product of atleast one factor pair. Eg- Factors of 438 are 1 , 2 , 3 , 6 , 73 , 146 , 219 , 438. So, factors of 438 in pair are (1,438), (2,219), (3,146), (6,73).

#### What is the definition of factors?

In mathematics, factors are number, algebraic expressions which when multiplied together produce desired product. A factor of a number can be positive or negative.

#### Properties of Factors

• Each number is a factor of itself. Eg. 438 is a factor of itself.
• 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, 6, 73, 146, 219, 438 are exact divisors of 438.
• 1 is a factor of every number. Eg. 1 is a factor of 438.
• Every number is a factor of zero (0), since 438 x 0 = 0.

#### Steps to find Factors of 438

• Step 1. Find all the numbers that would divide 438 without leaving any remainder. Starting with the number 1 upto 219 (half of 438). The number 1 and the number itself are always factors of the given number.
438 ÷ 1 : Remainder = 0
438 ÷ 2 : Remainder = 0
438 ÷ 3 : Remainder = 0
438 ÷ 6 : Remainder = 0
438 ÷ 73 : Remainder = 0
438 ÷ 146 : Remainder = 0
438 ÷ 219 : Remainder = 0
438 ÷ 438 : Remainder = 0

Hence, Factors of 438 are 1, 2, 3, 6, 73, 146, 219, and 438

• Is 438 a composite number?

Yes 438 is a composite number.

• Is 438 a prime number?

No 438 is not a prime number.

• What is the mean of factors of 438?

Factors of 438 are 1 , 2 , 3 , 6 , 73 , 146 , 219 , 438. therefore mean of factors of 438 is (1 + 2 + 3 + 6 + 73 + 146 + 219 + 438) / 8 = 111.00.

• 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.
