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 13,098,395, 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 | 13,098,395 | |
| -1 | -13,098,395 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,098,395.
Example:
1 x 13,098,395 = 13,098,395
and
-1 x -13,098,395 = 13,098,395
Notice both answers equal 13,098,395
With that explanation out of the way, let's continue. Next, we take the number 13,098,395 and divide it by 2:
13,098,395 ÷ 2 = 6,549,197.5
If the quotient is a whole number, then 2 and 6,549,197.5 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 | 13,098,395 | |
| -1 | -13,098,395 |
Now, we try dividing 13,098,395 by 3:
13,098,395 ÷ 3 = 4,366,131.6667
If the quotient is a whole number, then 3 and 4,366,131.6667 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 | 13,098,395 | |
| -1 | -13,098,395 |
Let's try dividing by 4:
13,098,395 ÷ 4 = 3,274,598.75
If the quotient is a whole number, then 4 and 3,274,598.75 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 | 13,098,395 | |
| -1 | 13,098,395 |
If you did it right, you will end up with this table:
| 1 | 5 | 97 | 113 | 239 | 485 | 565 | 1,195 | 10,961 | 23,183 | 27,007 | 54,805 | 115,915 | 135,035 | 2,619,679 | 13,098,395 |
| -1 | -5 | -97 | -113 | -239 | -485 | -565 | -1,195 | -10,961 | -23,183 | -27,007 | -54,805 | -115,915 | -135,035 | -2,619,679 | -13,098,395 |
