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 8,398,901, 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 | 8,398,901 | |
| -1 | -8,398,901 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,398,901.
Example:
1 x 8,398,901 = 8,398,901
and
-1 x -8,398,901 = 8,398,901
Notice both answers equal 8,398,901
With that explanation out of the way, let's continue. Next, we take the number 8,398,901 and divide it by 2:
8,398,901 ÷ 2 = 4,199,450.5
If the quotient is a whole number, then 2 and 4,199,450.5 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 | 8,398,901 | |
| -1 | -8,398,901 |
Now, we try dividing 8,398,901 by 3:
8,398,901 ÷ 3 = 2,799,633.6667
If the quotient is a whole number, then 3 and 2,799,633.6667 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 | 8,398,901 | |
| -1 | -8,398,901 |
Let's try dividing by 4:
8,398,901 ÷ 4 = 2,099,725.25
If the quotient is a whole number, then 4 and 2,099,725.25 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 | 8,398,901 | |
| -1 | 8,398,901 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 163 | 433 | 1,141 | 2,771 | 3,031 | 7,361 | 19,397 | 51,527 | 70,579 | 494,053 | 1,199,843 | 8,398,901 |
| -1 | -7 | -17 | -119 | -163 | -433 | -1,141 | -2,771 | -3,031 | -7,361 | -19,397 | -51,527 | -70,579 | -494,053 | -1,199,843 | -8,398,901 |
