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 9,279,385, 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 | 9,279,385 | |
| -1 | -9,279,385 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,279,385.
Example:
1 x 9,279,385 = 9,279,385
and
-1 x -9,279,385 = 9,279,385
Notice both answers equal 9,279,385
With that explanation out of the way, let's continue. Next, we take the number 9,279,385 and divide it by 2:
9,279,385 ÷ 2 = 4,639,692.5
If the quotient is a whole number, then 2 and 4,639,692.5 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 | 9,279,385 | |
| -1 | -9,279,385 |
Now, we try dividing 9,279,385 by 3:
9,279,385 ÷ 3 = 3,093,128.3333
If the quotient is a whole number, then 3 and 3,093,128.3333 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 | 9,279,385 | |
| -1 | -9,279,385 |
Let's try dividing by 4:
9,279,385 ÷ 4 = 2,319,846.25
If the quotient is a whole number, then 4 and 2,319,846.25 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 | 9,279,385 | |
| -1 | 9,279,385 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 131 | 155 | 457 | 655 | 2,285 | 4,061 | 14,167 | 20,305 | 59,867 | 70,835 | 299,335 | 1,855,877 | 9,279,385 |
| -1 | -5 | -31 | -131 | -155 | -457 | -655 | -2,285 | -4,061 | -14,167 | -20,305 | -59,867 | -70,835 | -299,335 | -1,855,877 | -9,279,385 |
