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 9,163,315, 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 | 9,163,315 | |
| -1 | -9,163,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,163,315.
Example:
1 x 9,163,315 = 9,163,315
and
-1 x -9,163,315 = 9,163,315
Notice both answers equal 9,163,315
With that explanation out of the way, let's continue. Next, we take the number 9,163,315 and divide it by 2:
9,163,315 ÷ 2 = 4,581,657.5
If the quotient is a whole number, then 2 and 4,581,657.5 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 | 9,163,315 | |
| -1 | -9,163,315 |
Now, we try dividing 9,163,315 by 3:
9,163,315 ÷ 3 = 3,054,438.3333
If the quotient is a whole number, then 3 and 3,054,438.3333 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 | 9,163,315 | |
| -1 | -9,163,315 |
Let's try dividing by 4:
9,163,315 ÷ 4 = 2,290,828.75
If the quotient is a whole number, then 4 and 2,290,828.75 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 | 9,163,315 | |
| -1 | 9,163,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 23 | 35 | 115 | 161 | 805 | 11,383 | 56,915 | 79,681 | 261,809 | 398,405 | 1,309,045 | 1,832,663 | 9,163,315 |
| -1 | -5 | -7 | -23 | -35 | -115 | -161 | -805 | -11,383 | -56,915 | -79,681 | -261,809 | -398,405 | -1,309,045 | -1,832,663 | -9,163,315 |
