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 11,702,585, 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 | 11,702,585 | |
| -1 | -11,702,585 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,702,585.
Example:
1 x 11,702,585 = 11,702,585
and
-1 x -11,702,585 = 11,702,585
Notice both answers equal 11,702,585
With that explanation out of the way, let's continue. Next, we take the number 11,702,585 and divide it by 2:
11,702,585 ÷ 2 = 5,851,292.5
If the quotient is a whole number, then 2 and 5,851,292.5 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 | 11,702,585 | |
| -1 | -11,702,585 |
Now, we try dividing 11,702,585 by 3:
11,702,585 ÷ 3 = 3,900,861.6667
If the quotient is a whole number, then 3 and 3,900,861.6667 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 | 11,702,585 | |
| -1 | -11,702,585 |
Let's try dividing by 4:
11,702,585 ÷ 4 = 2,925,646.25
If the quotient is a whole number, then 4 and 2,925,646.25 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 | 11,702,585 | |
| -1 | 11,702,585 |
If you did it right, you will end up with this table:
| 1 | 5 | 83 | 163 | 173 | 415 | 815 | 865 | 13,529 | 14,359 | 28,199 | 67,645 | 71,795 | 140,995 | 2,340,517 | 11,702,585 |
| -1 | -5 | -83 | -163 | -173 | -415 | -815 | -865 | -13,529 | -14,359 | -28,199 | -67,645 | -71,795 | -140,995 | -2,340,517 | -11,702,585 |
