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 8,676,871, 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 | 8,676,871 | |
| -1 | -8,676,871 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,676,871.
Example:
1 x 8,676,871 = 8,676,871
and
-1 x -8,676,871 = 8,676,871
Notice both answers equal 8,676,871
With that explanation out of the way, let's continue. Next, we take the number 8,676,871 and divide it by 2:
8,676,871 ÷ 2 = 4,338,435.5
If the quotient is a whole number, then 2 and 4,338,435.5 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 | 8,676,871 | |
| -1 | -8,676,871 |
Now, we try dividing 8,676,871 by 3:
8,676,871 ÷ 3 = 2,892,290.3333
If the quotient is a whole number, then 3 and 2,892,290.3333 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 | 8,676,871 | |
| -1 | -8,676,871 |
Let's try dividing by 4:
8,676,871 ÷ 4 = 2,169,217.75
If the quotient is a whole number, then 4 and 2,169,217.75 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 | 8,676,871 | |
| -1 | 8,676,871 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 49 | 287 | 343 | 617 | 2,009 | 4,319 | 14,063 | 25,297 | 30,233 | 177,079 | 211,631 | 1,239,553 | 8,676,871 |
| -1 | -7 | -41 | -49 | -287 | -343 | -617 | -2,009 | -4,319 | -14,063 | -25,297 | -30,233 | -177,079 | -211,631 | -1,239,553 | -8,676,871 |
