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 8,580,335, 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 | 8,580,335 | |
| -1 | -8,580,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,580,335.
Example:
1 x 8,580,335 = 8,580,335
and
-1 x -8,580,335 = 8,580,335
Notice both answers equal 8,580,335
With that explanation out of the way, let's continue. Next, we take the number 8,580,335 and divide it by 2:
8,580,335 ÷ 2 = 4,290,167.5
If the quotient is a whole number, then 2 and 4,290,167.5 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 | 8,580,335 | |
| -1 | -8,580,335 |
Now, we try dividing 8,580,335 by 3:
8,580,335 ÷ 3 = 2,860,111.6667
If the quotient is a whole number, then 3 and 2,860,111.6667 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 | 8,580,335 | |
| -1 | -8,580,335 |
Let's try dividing by 4:
8,580,335 ÷ 4 = 2,145,083.75
If the quotient is a whole number, then 4 and 2,145,083.75 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 | 8,580,335 | |
| -1 | 8,580,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 155 | 197 | 281 | 985 | 1,405 | 6,107 | 8,711 | 30,535 | 43,555 | 55,357 | 276,785 | 1,716,067 | 8,580,335 |
| -1 | -5 | -31 | -155 | -197 | -281 | -985 | -1,405 | -6,107 | -8,711 | -30,535 | -43,555 | -55,357 | -276,785 | -1,716,067 | -8,580,335 |
