### Example: Find factors of 143 in pair

Factor Pair Pair Factorization
1 and 143 1 x 143 = 143
11 and 13 11 x 13 = 143

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 143. They are called negative pair factors.

Hence, the negative pairs of 143 would be ( -1 , -143 ) .

#### 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 143 are 1 , 11 , 13 , 143. So, factors of 143 in pair are (1,143), (11,13).

#### 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 number is a factor of zero (0), since 143 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, 11, 13, 143 are exact divisors of 143.
• Factors of 143 are 1, 11, 13, 143. Each factor divides 143 without leaving a remainder.

#### Steps to find Factors of 143

• Step 1. Find all the numbers that would divide 143 without leaving any remainder. Starting with the number 1 upto 71 (half of 143). The number 1 and the number itself are always factors of the given number.
143 ÷ 1 : Remainder = 0
143 ÷ 11 : Remainder = 0
143 ÷ 13 : Remainder = 0
143 ÷ 143 : Remainder = 0

Hence, Factors of 143 are 1, 11, 13, and 143

• Is 143 a perfect square?

No 143 is not a perfect square.

• Write five multiples of 143.

Five multiples of 143 are 286, 429, 572, 715, 858.

• Is there any even prime factor of 143?

No there is no even prime factor, i.e. 2, of 143.

• 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.

#### Examples of Factors

How many total number of factors of 143 in pair are possible?

Factors of 143 are 1, 11, 13, 143. Hence, the factors of 143 in pair are (1,143), (11,13). Therefore, in total 2 pairs of factors are possible.

Help Deep in writing the positive factors of 143 in pair and negative factor of 143 in pair.

Factors of 143 are 1, 11, 13, 143. Positive factors of 143 in pair are (1,143), (11,13). Negative factors of 143 in pair are (-1,-143), (-11,-13).

Find the product of all factors of 143.

Factors of 143 are 1, 11, 13, 143. So the product of all factors of 143 would be 1 x 11 x 13 x 143 = 20449.

Find the product of all prime factors of 143.

Factors of 143 are 1, 11, 13, 143. Prime factors are 11, 13. So, the product of all prime factors of 143 would be 11 x 13 = 143.
