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 8100. They are called negative pair factors.

Hence, the negative pairs of 8100 would be ( -1 , -8100 ) .

Definition of factor pairs?

In mathematics, factor pair are often given as pair of numbers which when multiplied together give the original number. Every natural number is a product of atleast one factor pair. Eg- Factors of 8100 are 1 , 2 , 3 , 4 , 5 , 6 , 9 , 10 , 12 , 15 , 18 , 20 , 25 , 27 , 30 , 36 , 45 , 50 , 54 , 60 , 75 , 81 , 90 , 100 , 108 , 135 , 150 , 162 , 180 , 225 , 270 , 300 , 324 , 405 , 450 , 540 , 675 , 810 , 900 , 1350 , 1620 , 2025 , 2700 , 4050 , 8100. So, factors of 8100 in pair are (1,8100), (2,4050), (3,2700), (4,2025), (5,1620), (6,1350), (9,900), (10,810), (12,675), (15,540), (18,450), (20,405), (25,324), (27,300), (30,270), (36,225), (45,180), (50,162), (54,150), (60,135), (75,108), (81,100), (90,90).

What are factors?

In mathematics, a factor is that number which divides into another number exactly, without leaving a remainder. A factor of a number can be positive or negative.

Properties of Factors

  • Each number is a factor of itself. Eg. 8100 is a factor of itself.
  • 1 is a factor of every number. Eg. 1 is a factor of 8100.
  • Every number is a factor of zero (0), since 8100 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, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 27, 30, 36, 45, 50, 54, 60, 75, 81, 90, 100, 108, 135, 150, 162, 180, 225, 270, 300, 324, 405, 450, 540, 675, 810, 900, 1350, 1620, 2025, 2700, 4050, 8100 are exact divisors of 8100.
  • Factors of 8100 are 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 27, 30, 36, 45, 50, 54, 60, 75, 81, 90, 100, 108, 135, 150, 162, 180, 225, 270, 300, 324, 405, 450, 540, 675, 810, 900, 1350, 1620, 2025, 2700, 4050, 8100. Each factor divides 8100 without leaving a remainder.
  • Every factor of a number is less than or equal to the number, eg. 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 27, 30, 36, 45, 50, 54, 60, 75, 81, 90, 100, 108, 135, 150, 162, 180, 225, 270, 300, 324, 405, 450, 540, 675, 810, 900, 1350, 1620, 2025, 2700, 4050, 8100 are all less than or equal to 8100.
