 1.   Steps to find factors of 133 in pair 2.   What is factors of a number in pair? 3.   What are Factors? 4.   Frequently Asked Questions 5.   Examples of factors in pair

### Example: Find factors of 133 in pair

Factor Pair Pair Factorization
1 and 133 1 x 133 = 133
7 and 19 7 x 19 = 133

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 133. They are called negative pair factors.

Hence, the negative pairs of 133 would be ( -1 , -133 ) .

#### 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 133 are 1 , 7 , 19 , 133. So, factors of 133 in pair are (1,133), (7,19).

#### 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

• Every factor of a number is an exact divisor of that number, example 1, 7, 19, 133 are exact divisors of 133.
• Every number other than 1 has at least two factors, namely the number itself and 1.
• Each number is a factor of itself. Eg. 133 is a factor of itself.
• 1 is a factor of every number. Eg. 1 is a factor of 133.

#### Steps to find Factors of 133

• Step 1. Find all the numbers that would divide 133 without leaving any remainder. Starting with the number 1 upto 66 (half of 133). The number 1 and the number itself are always factors of the given number.
133 ÷ 1 : Remainder = 0
133 ÷ 7 : Remainder = 0
133 ÷ 19 : Remainder = 0
133 ÷ 133 : Remainder = 0

Hence, Factors of 133 are 1, 7, 19, and 133

• Is there any even prime factor of 133?

No there is no even prime factor, i.e. 2, of 133.

• What is the mean of all prime factors of 133?

Factors of 133 are 1 , 7 , 19 , 133. Prime factors of 133 are 7 , 19. Therefore mean of prime factors of 133 is (7 + 19) / 2 = 13.00.

• What is the mean of factors of 133?

Factors of 133 are 1 , 7 , 19 , 133. therefore mean of factors of 133 is (1 + 7 + 19 + 133) / 4 = 40.00.

• 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.
