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 10,671,661, 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 | 10,671,661 | |
| -1 | -10,671,661 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,671,661.
Example:
1 x 10,671,661 = 10,671,661
and
-1 x -10,671,661 = 10,671,661
Notice both answers equal 10,671,661
With that explanation out of the way, let's continue. Next, we take the number 10,671,661 and divide it by 2:
10,671,661 ÷ 2 = 5,335,830.5
If the quotient is a whole number, then 2 and 5,335,830.5 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 | 10,671,661 | |
| -1 | -10,671,661 |
Now, we try dividing 10,671,661 by 3:
10,671,661 ÷ 3 = 3,557,220.3333
If the quotient is a whole number, then 3 and 3,557,220.3333 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 | 10,671,661 | |
| -1 | -10,671,661 |
Let's try dividing by 4:
10,671,661 ÷ 4 = 2,667,915.25
If the quotient is a whole number, then 4 and 2,667,915.25 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 | 10,671,661 | |
| -1 | 10,671,661 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 49 | 77 | 91 | 143 | 539 | 637 | 1,001 | 1,523 | 7,007 | 10,661 | 16,753 | 19,799 | 74,627 | 117,271 | 138,593 | 217,789 | 820,897 | 970,151 | 1,524,523 | 10,671,661 |
| -1 | -7 | -11 | -13 | -49 | -77 | -91 | -143 | -539 | -637 | -1,001 | -1,523 | -7,007 | -10,661 | -16,753 | -19,799 | -74,627 | -117,271 | -138,593 | -217,789 | -820,897 | -970,151 | -1,524,523 | -10,671,661 |
