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 8,710,871, 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 | 8,710,871 | |
| -1 | -8,710,871 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,710,871.
Example:
1 x 8,710,871 = 8,710,871
and
-1 x -8,710,871 = 8,710,871
Notice both answers equal 8,710,871
With that explanation out of the way, let's continue. Next, we take the number 8,710,871 and divide it by 2:
8,710,871 ÷ 2 = 4,355,435.5
If the quotient is a whole number, then 2 and 4,355,435.5 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 | 8,710,871 | |
| -1 | -8,710,871 |
Now, we try dividing 8,710,871 by 3:
8,710,871 ÷ 3 = 2,903,623.6667
If the quotient is a whole number, then 3 and 2,903,623.6667 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 | 8,710,871 | |
| -1 | -8,710,871 |
Let's try dividing by 4:
8,710,871 ÷ 4 = 2,177,717.75
If the quotient is a whole number, then 4 and 2,177,717.75 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 | 8,710,871 | |
| -1 | 8,710,871 |
If you did it right, you will end up with this table:
| 1 | 13 | 67 | 73 | 137 | 871 | 949 | 1,781 | 4,891 | 9,179 | 10,001 | 63,583 | 119,327 | 130,013 | 670,067 | 8,710,871 |
| -1 | -13 | -67 | -73 | -137 | -871 | -949 | -1,781 | -4,891 | -9,179 | -10,001 | -63,583 | -119,327 | -130,013 | -670,067 | -8,710,871 |
