### Example: Find factors of 1287 in pair

Factor Pair Pair Factorization
1 and 1287 1 x 1287 = 1287
3 and 429 3 x 429 = 1287
9 and 143 9 x 143 = 1287
11 and 117 11 x 117 = 1287
13 and 99 13 x 99 = 1287
33 and 39 33 x 39 = 1287

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 1287. They are called negative pair factors.

Hence, the negative pairs of 1287 would be ( -1 , -1287 ) .

#### 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 1287 are 1 , 3 , 9 , 11 , 13 , 33 , 39 , 99 , 117 , 143 , 429 , 1287. So, factors of 1287 in pair are (1,1287), (3,429), (9,143), (11,117), (13,99), (33,39).

#### 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 1287 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, 9, 11, 13, 33, 39, 99, 117, 143, 429, 1287 are exact divisors of 1287.
• Factors of 1287 are 1, 3, 9, 11, 13, 33, 39, 99, 117, 143, 429, 1287. Each factor divides 1287 without leaving a remainder.

#### Steps to find Factors of 1287

• Step 1. Find all the numbers that would divide 1287 without leaving any remainder. Starting with the number 1 upto 643 (half of 1287). The number 1 and the number itself are always factors of the given number.
1287 ÷ 1 : Remainder = 0
1287 ÷ 3 : Remainder = 0
1287 ÷ 9 : Remainder = 0
1287 ÷ 11 : Remainder = 0
1287 ÷ 13 : Remainder = 0
1287 ÷ 33 : Remainder = 0
1287 ÷ 39 : Remainder = 0
1287 ÷ 99 : Remainder = 0
1287 ÷ 117 : Remainder = 0
1287 ÷ 143 : Remainder = 0
1287 ÷ 429 : Remainder = 0
1287 ÷ 1287 : Remainder = 0

Hence, Factors of 1287 are 1, 3, 9, 11, 13, 33, 39, 99, 117, 143, 429, and 1287
