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 11,641,663, 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 | 11,641,663 | |
| -1 | -11,641,663 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,641,663.
Example:
1 x 11,641,663 = 11,641,663
and
-1 x -11,641,663 = 11,641,663
Notice both answers equal 11,641,663
With that explanation out of the way, let's continue. Next, we take the number 11,641,663 and divide it by 2:
11,641,663 ÷ 2 = 5,820,831.5
If the quotient is a whole number, then 2 and 5,820,831.5 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 | 11,641,663 | |
| -1 | -11,641,663 |
Now, we try dividing 11,641,663 by 3:
11,641,663 ÷ 3 = 3,880,554.3333
If the quotient is a whole number, then 3 and 3,880,554.3333 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 | 11,641,663 | |
| -1 | -11,641,663 |
Let's try dividing by 4:
11,641,663 ÷ 4 = 2,910,415.75
If the quotient is a whole number, then 4 and 2,910,415.75 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 | 11,641,663 | |
| -1 | 11,641,663 |
If you did it right, you will end up with this table:
| 1 | 11 | 41 | 83 | 311 | 451 | 913 | 3,403 | 3,421 | 12,751 | 25,813 | 37,433 | 140,261 | 283,943 | 1,058,333 | 11,641,663 |
| -1 | -11 | -41 | -83 | -311 | -451 | -913 | -3,403 | -3,421 | -12,751 | -25,813 | -37,433 | -140,261 | -283,943 | -1,058,333 | -11,641,663 |
