Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 11,144,231, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 11,144,231 | |
| -1 | -11,144,231 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,144,231.
Example:
1 x 11,144,231 = 11,144,231
and
-1 x -11,144,231 = 11,144,231
Notice both answers equal 11,144,231
With that explanation out of the way, let's continue. Next, we take the number 11,144,231 and divide it by 2:
11,144,231 ÷ 2 = 5,572,115.5
If the quotient is a whole number, then 2 and 5,572,115.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 11,144,231 | |
| -1 | -11,144,231 |
Now, we try dividing 11,144,231 by 3:
11,144,231 ÷ 3 = 3,714,743.6667
If the quotient is a whole number, then 3 and 3,714,743.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 11,144,231 | |
| -1 | -11,144,231 |
Let's try dividing by 4:
11,144,231 ÷ 4 = 2,786,057.75
If the quotient is a whole number, then 4 and 2,786,057.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 11,144,231 | |
| -1 | 11,144,231 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 71 | 119 | 497 | 1,207 | 1,319 | 8,449 | 9,233 | 22,423 | 93,649 | 156,961 | 655,543 | 1,592,033 | 11,144,231 |
| -1 | -7 | -17 | -71 | -119 | -497 | -1,207 | -1,319 | -8,449 | -9,233 | -22,423 | -93,649 | -156,961 | -655,543 | -1,592,033 | -11,144,231 |
