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 9,381,065, 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 | 9,381,065 | |
| -1 | -9,381,065 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,381,065.
Example:
1 x 9,381,065 = 9,381,065
and
-1 x -9,381,065 = 9,381,065
Notice both answers equal 9,381,065
With that explanation out of the way, let's continue. Next, we take the number 9,381,065 and divide it by 2:
9,381,065 ÷ 2 = 4,690,532.5
If the quotient is a whole number, then 2 and 4,690,532.5 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 | 9,381,065 | |
| -1 | -9,381,065 |
Now, we try dividing 9,381,065 by 3:
9,381,065 ÷ 3 = 3,127,021.6667
If the quotient is a whole number, then 3 and 3,127,021.6667 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 | 9,381,065 | |
| -1 | -9,381,065 |
Let's try dividing by 4:
9,381,065 ÷ 4 = 2,345,266.25
If the quotient is a whole number, then 4 and 2,345,266.25 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 | 9,381,065 | |
| -1 | 9,381,065 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 31 | 145 | 155 | 899 | 2,087 | 4,495 | 10,435 | 60,523 | 64,697 | 302,615 | 323,485 | 1,876,213 | 9,381,065 |
| -1 | -5 | -29 | -31 | -145 | -155 | -899 | -2,087 | -4,495 | -10,435 | -60,523 | -64,697 | -302,615 | -323,485 | -1,876,213 | -9,381,065 |
