5. Factor Pairs of 100 example
5. Find Factor Pairs of 100
Solution:
The factor pairs of 100 are pair of numbers, which are multiplied together resulting in 100
The factor pairs of 100 can be either positive pair or negative pair
Positive factor pairs of 100 :
| 1 | `xx` | 100 | = | 100 | `=>` | (1, 100) | | 2 | `xx` | 50 | = | 100 | `=>` | (2, 50) | | 4 | `xx` | 25 | = | 100 | `=>` | (4, 25) | | 5 | `xx` | 20 | = | 100 | `=>` | (5, 20) | | 10 | `xx` | 10 | = | 100 | `=>` | (10, 10) | | 20 | `xx` | 5 | = | 100 | `=>` | (20, 5) |
Since `20` and `5` are already factors of `100`, so we stop here
Hence, Positive factor pairs of 100 are
`(1, 100),(2, 50),(4, 25),(5, 20),(10, 10)`
Negative factor pairs of 100 :
| -1 | `xx` | -100 | = | 100 | `=>` | (-1, -100) | | -2 | `xx` | -50 | = | 100 | `=>` | (-2, -50) | | -4 | `xx` | -25 | = | 100 | `=>` | (-4, -25) | | -5 | `xx` | -20 | = | 100 | `=>` | (-5, -20) | | -10 | `xx` | -10 | = | 100 | `=>` | (-10, -10) | | -20 | `xx` | -5 | = | 100 | `=>` | (-20, -5) |
Since `-20` and `-5` are already factors of `100`, so we stop here
Hence, Negative factor pairs of 100 are
`(-1, -100),(-2, -50),(-4, -25),(-5, -20),(-10, -10)`
