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 8,870,315, 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 | 8,870,315 | |
| -1 | -8,870,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,870,315.
Example:
1 x 8,870,315 = 8,870,315
and
-1 x -8,870,315 = 8,870,315
Notice both answers equal 8,870,315
With that explanation out of the way, let's continue. Next, we take the number 8,870,315 and divide it by 2:
8,870,315 ÷ 2 = 4,435,157.5
If the quotient is a whole number, then 2 and 4,435,157.5 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 | 8,870,315 | |
| -1 | -8,870,315 |
Now, we try dividing 8,870,315 by 3:
8,870,315 ÷ 3 = 2,956,771.6667
If the quotient is a whole number, then 3 and 2,956,771.6667 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 | 8,870,315 | |
| -1 | -8,870,315 |
Let's try dividing by 4:
8,870,315 ÷ 4 = 2,217,578.75
If the quotient is a whole number, then 4 and 2,217,578.75 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 | 8,870,315 | |
| -1 | 8,870,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 61 | 127 | 229 | 305 | 635 | 1,145 | 7,747 | 13,969 | 29,083 | 38,735 | 69,845 | 145,415 | 1,774,063 | 8,870,315 |
| -1 | -5 | -61 | -127 | -229 | -305 | -635 | -1,145 | -7,747 | -13,969 | -29,083 | -38,735 | -69,845 | -145,415 | -1,774,063 | -8,870,315 |
