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 8,870,855, 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 | 8,870,855 | |
| -1 | -8,870,855 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,870,855.
Example:
1 x 8,870,855 = 8,870,855
and
-1 x -8,870,855 = 8,870,855
Notice both answers equal 8,870,855
With that explanation out of the way, let's continue. Next, we take the number 8,870,855 and divide it by 2:
8,870,855 ÷ 2 = 4,435,427.5
If the quotient is a whole number, then 2 and 4,435,427.5 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 | 8,870,855 | |
| -1 | -8,870,855 |
Now, we try dividing 8,870,855 by 3:
8,870,855 ÷ 3 = 2,956,951.6667
If the quotient is a whole number, then 3 and 2,956,951.6667 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 | 8,870,855 | |
| -1 | -8,870,855 |
Let's try dividing by 4:
8,870,855 ÷ 4 = 2,217,713.75
If the quotient is a whole number, then 4 and 2,217,713.75 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 | 8,870,855 | |
| -1 | 8,870,855 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 85 | 119 | 289 | 595 | 877 | 1,445 | 2,023 | 4,385 | 6,139 | 10,115 | 14,909 | 30,695 | 74,545 | 104,363 | 253,453 | 521,815 | 1,267,265 | 1,774,171 | 8,870,855 |
| -1 | -5 | -7 | -17 | -35 | -85 | -119 | -289 | -595 | -877 | -1,445 | -2,023 | -4,385 | -6,139 | -10,115 | -14,909 | -30,695 | -74,545 | -104,363 | -253,453 | -521,815 | -1,267,265 | -1,774,171 | -8,870,855 |
