| Factor Pair | Pair Factorization |
|---|---|
| 1 and 405 | 1 x 405 = 405 |
| 3 and 135 | 3 x 135 = 405 |
| 5 and 81 | 5 x 81 = 405 |
| 9 and 45 | 9 x 45 = 405 |
| 15 and 27 | 15 x 27 = 405 |
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 405. They are called negative pair factors.
Hence, the negative pairs of 405 would be ( -1 , -405 ) .
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 405 are 1 , 3 , 5 , 9 , 15 , 27 , 45 , 81 , 135 , 405. So, factors of 405 in pair are (1,405), (3,135), (5,81), (9,45), (15,27).
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.
Hence, Factors of 405 are 1, 3, 5, 9, 15, 27, 45, 81, 135, and 405
