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