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 9,890,507, 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 | 9,890,507 | |
| -1 | -9,890,507 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,890,507.
Example:
1 x 9,890,507 = 9,890,507
and
-1 x -9,890,507 = 9,890,507
Notice both answers equal 9,890,507
With that explanation out of the way, let's continue. Next, we take the number 9,890,507 and divide it by 2:
9,890,507 ÷ 2 = 4,945,253.5
If the quotient is a whole number, then 2 and 4,945,253.5 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 | 9,890,507 | |
| -1 | -9,890,507 |
Now, we try dividing 9,890,507 by 3:
9,890,507 ÷ 3 = 3,296,835.6667
If the quotient is a whole number, then 3 and 3,296,835.6667 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 | 9,890,507 | |
| -1 | -9,890,507 |
Let's try dividing by 4:
9,890,507 ÷ 4 = 2,472,626.75
If the quotient is a whole number, then 4 and 2,472,626.75 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 | 9,890,507 | |
| -1 | 9,890,507 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 37 | 209 | 407 | 703 | 1,279 | 7,733 | 14,069 | 24,301 | 47,323 | 267,311 | 520,553 | 899,137 | 9,890,507 |
| -1 | -11 | -19 | -37 | -209 | -407 | -703 | -1,279 | -7,733 | -14,069 | -24,301 | -47,323 | -267,311 | -520,553 | -899,137 | -9,890,507 |
