Calculate Pair Factors of
1 x 4=4
2 x 2=4
So Pair Factors of 4 are
(1,4)
(2,2)
In Mathematics, factor pairs of a number can be defined as a pair of numbers that when multiplied gives the original number. Every number has a pair factor which when multiplied together gives the original number.
Factor pairs are also written in positive and negative pairs. Let’s understand this concept with an example.
Example:
What are the factor pairs of 42?
The factor pairs of 42 are the pair of numbers that when multiplied give the original number. 42. The factor pairs of 42 can be both positive and negative. Let’s find the positive and negative factor pairs of 42.
The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. Positive factor pairs of 42:
1 X 42 = 42 | 42 X 1 = 42 |
2 X 21 = 42 | 21 X 2 = 42 |
3 X 14 = 42 | 14 X 3 = 42 |
6 X 7 = 42 | 7 X 6 = 42 |
The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. Negative factor pairs of 42:
-1 X -42 = -42 | -42 X -1 = -42 |
-2 X -21 = -42 | -21 X -2 = -42 |
-3 X -14 = -42 | -14 X -3 = -42 |
-6 X -7 = -42 | -7 X -6 = -42 |
