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 9,598,421, 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 | 9,598,421 | |
| -1 | -9,598,421 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,598,421.
Example:
1 x 9,598,421 = 9,598,421
and
-1 x -9,598,421 = 9,598,421
Notice both answers equal 9,598,421
With that explanation out of the way, let's continue. Next, we take the number 9,598,421 and divide it by 2:
9,598,421 ÷ 2 = 4,799,210.5
If the quotient is a whole number, then 2 and 4,799,210.5 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 | 9,598,421 | |
| -1 | -9,598,421 |
Now, we try dividing 9,598,421 by 3:
9,598,421 ÷ 3 = 3,199,473.6667
If the quotient is a whole number, then 3 and 3,199,473.6667 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 | 9,598,421 | |
| -1 | -9,598,421 |
Let's try dividing by 4:
9,598,421 ÷ 4 = 2,399,605.25
If the quotient is a whole number, then 4 and 2,399,605.25 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 | 9,598,421 | |
| -1 | 9,598,421 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 79 | 119 | 553 | 1,021 | 1,343 | 7,147 | 9,401 | 17,357 | 80,659 | 121,499 | 564,613 | 1,371,203 | 9,598,421 |
| -1 | -7 | -17 | -79 | -119 | -553 | -1,021 | -1,343 | -7,147 | -9,401 | -17,357 | -80,659 | -121,499 | -564,613 | -1,371,203 | -9,598,421 |
