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 8,521,835, 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 | 8,521,835 | |
| -1 | -8,521,835 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,521,835.
Example:
1 x 8,521,835 = 8,521,835
and
-1 x -8,521,835 = 8,521,835
Notice both answers equal 8,521,835
With that explanation out of the way, let's continue. Next, we take the number 8,521,835 and divide it by 2:
8,521,835 ÷ 2 = 4,260,917.5
If the quotient is a whole number, then 2 and 4,260,917.5 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 | 8,521,835 | |
| -1 | -8,521,835 |
Now, we try dividing 8,521,835 by 3:
8,521,835 ÷ 3 = 2,840,611.6667
If the quotient is a whole number, then 3 and 2,840,611.6667 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 | 8,521,835 | |
| -1 | -8,521,835 |
Let's try dividing by 4:
8,521,835 ÷ 4 = 2,130,458.75
If the quotient is a whole number, then 4 and 2,130,458.75 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 | 8,521,835 | |
| -1 | 8,521,835 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 245 | 343 | 1,715 | 4,969 | 24,845 | 34,783 | 173,915 | 243,481 | 1,217,405 | 1,704,367 | 8,521,835 |
| -1 | -5 | -7 | -35 | -49 | -245 | -343 | -1,715 | -4,969 | -24,845 | -34,783 | -173,915 | -243,481 | -1,217,405 | -1,704,367 | -8,521,835 |
