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 8,700,335, 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 | 8,700,335 | |
| -1 | -8,700,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,700,335.
Example:
1 x 8,700,335 = 8,700,335
and
-1 x -8,700,335 = 8,700,335
Notice both answers equal 8,700,335
With that explanation out of the way, let's continue. Next, we take the number 8,700,335 and divide it by 2:
8,700,335 ÷ 2 = 4,350,167.5
If the quotient is a whole number, then 2 and 4,350,167.5 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 | 8,700,335 | |
| -1 | -8,700,335 |
Now, we try dividing 8,700,335 by 3:
8,700,335 ÷ 3 = 2,900,111.6667
If the quotient is a whole number, then 3 and 2,900,111.6667 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 | 8,700,335 | |
| -1 | -8,700,335 |
Let's try dividing by 4:
8,700,335 ÷ 4 = 2,175,083.75
If the quotient is a whole number, then 4 and 2,175,083.75 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 | 8,700,335 | |
| -1 | 8,700,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 331 | 751 | 1,655 | 2,317 | 3,755 | 5,257 | 11,585 | 26,285 | 248,581 | 1,242,905 | 1,740,067 | 8,700,335 |
| -1 | -5 | -7 | -35 | -331 | -751 | -1,655 | -2,317 | -3,755 | -5,257 | -11,585 | -26,285 | -248,581 | -1,242,905 | -1,740,067 | -8,700,335 |
