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 9,869,299, 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 | 9,869,299 | |
| -1 | -9,869,299 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,869,299.
Example:
1 x 9,869,299 = 9,869,299
and
-1 x -9,869,299 = 9,869,299
Notice both answers equal 9,869,299
With that explanation out of the way, let's continue. Next, we take the number 9,869,299 and divide it by 2:
9,869,299 ÷ 2 = 4,934,649.5
If the quotient is a whole number, then 2 and 4,934,649.5 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 | 9,869,299 | |
| -1 | -9,869,299 |
Now, we try dividing 9,869,299 by 3:
9,869,299 ÷ 3 = 3,289,766.3333
If the quotient is a whole number, then 3 and 3,289,766.3333 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 | 9,869,299 | |
| -1 | -9,869,299 |
Let's try dividing by 4:
9,869,299 ÷ 4 = 2,467,324.75
If the quotient is a whole number, then 4 and 2,467,324.75 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 | 9,869,299 | |
| -1 | 9,869,299 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 89 | 187 | 593 | 979 | 1,513 | 6,523 | 10,081 | 16,643 | 52,777 | 110,891 | 580,547 | 897,209 | 9,869,299 |
| -1 | -11 | -17 | -89 | -187 | -593 | -979 | -1,513 | -6,523 | -10,081 | -16,643 | -52,777 | -110,891 | -580,547 | -897,209 | -9,869,299 |
