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 9,425,905, 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 | 9,425,905 | |
| -1 | -9,425,905 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,425,905.
Example:
1 x 9,425,905 = 9,425,905
and
-1 x -9,425,905 = 9,425,905
Notice both answers equal 9,425,905
With that explanation out of the way, let's continue. Next, we take the number 9,425,905 and divide it by 2:
9,425,905 ÷ 2 = 4,712,952.5
If the quotient is a whole number, then 2 and 4,712,952.5 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 | 9,425,905 | |
| -1 | -9,425,905 |
Now, we try dividing 9,425,905 by 3:
9,425,905 ÷ 3 = 3,141,968.3333
If the quotient is a whole number, then 3 and 3,141,968.3333 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 | 9,425,905 | |
| -1 | -9,425,905 |
Let's try dividing by 4:
9,425,905 ÷ 4 = 2,356,476.25
If the quotient is a whole number, then 4 and 2,356,476.25 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 | 9,425,905 | |
| -1 | 9,425,905 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 173 | 641 | 865 | 2,941 | 3,205 | 10,897 | 14,705 | 54,485 | 110,893 | 554,465 | 1,885,181 | 9,425,905 |
| -1 | -5 | -17 | -85 | -173 | -641 | -865 | -2,941 | -3,205 | -10,897 | -14,705 | -54,485 | -110,893 | -554,465 | -1,885,181 | -9,425,905 |
