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 10,645,165, 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 | 10,645,165 | |
| -1 | -10,645,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,645,165.
Example:
1 x 10,645,165 = 10,645,165
and
-1 x -10,645,165 = 10,645,165
Notice both answers equal 10,645,165
With that explanation out of the way, let's continue. Next, we take the number 10,645,165 and divide it by 2:
10,645,165 ÷ 2 = 5,322,582.5
If the quotient is a whole number, then 2 and 5,322,582.5 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 | 10,645,165 | |
| -1 | -10,645,165 |
Now, we try dividing 10,645,165 by 3:
10,645,165 ÷ 3 = 3,548,388.3333
If the quotient is a whole number, then 3 and 3,548,388.3333 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 | 10,645,165 | |
| -1 | -10,645,165 |
Let's try dividing by 4:
10,645,165 ÷ 4 = 2,661,291.25
If the quotient is a whole number, then 4 and 2,661,291.25 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 | 10,645,165 | |
| -1 | 10,645,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 83 | 113 | 227 | 415 | 565 | 1,135 | 9,379 | 18,841 | 25,651 | 46,895 | 94,205 | 128,255 | 2,129,033 | 10,645,165 |
| -1 | -5 | -83 | -113 | -227 | -415 | -565 | -1,135 | -9,379 | -18,841 | -25,651 | -46,895 | -94,205 | -128,255 | -2,129,033 | -10,645,165 |
