### Example: Find factors of 147 in pair

Factor Pair Pair Factorization
1 and 147 1 x 147 = 147
3 and 49 3 x 49 = 147
7 and 21 7 x 21 = 147

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 147. They are called negative pair factors.

Hence, the negative pairs of 147 would be ( -1 , -147 ) .

#### 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 147 are 1 , 3 , 7 , 21 , 49 , 147. So, factors of 147 in pair are (1,147), (3,49), (7,21).

#### 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 number is a factor of zero (0), since 147 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, 3, 7, 21, 49, 147 are exact divisors of 147.
• Factors of 147 are 1, 3, 7, 21, 49, 147. Each factor divides 147 without leaving a remainder.

#### Steps to find Factors of 147

• Step 1. Find all the numbers that would divide 147 without leaving any remainder. Starting with the number 1 upto 73 (half of 147). The number 1 and the number itself are always factors of the given number.
147 ÷ 1 : Remainder = 0
147 ÷ 3 : Remainder = 0
147 ÷ 7 : Remainder = 0
147 ÷ 21 : Remainder = 0
147 ÷ 49 : Remainder = 0
147 ÷ 147 : Remainder = 0

Hence, Factors of 147 are 1, 3, 7, 21, 49, and 147

• Is 147 a composite number?

Yes 147 is a composite number.

• Is 147 a perfect square?

No 147 is not a perfect square.

• Write all odd factors of 147?

The factors of 147 are 1, 3, 7, 21, 49, 147.
Odd factors of 147 are 1 , 3 , 7 , 21 , 49 , 147.

• What is the mean of all prime factors of 147?

Factors of 147 are 1 , 3 , 7 , 21 , 49 , 147. Prime factors of 147 are 3 , 7 , 7. Therefore mean of prime factors of 147 is (3 + 7 + 7) / 3 = 5.67.

• 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.
