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 3,586,385, 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 | 3,586,385 | |
| -1 | -3,586,385 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,586,385.
Example:
1 x 3,586,385 = 3,586,385
and
-1 x -3,586,385 = 3,586,385
Notice both answers equal 3,586,385
With that explanation out of the way, let's continue. Next, we take the number 3,586,385 and divide it by 2:
3,586,385 ÷ 2 = 1,793,192.5
If the quotient is a whole number, then 2 and 1,793,192.5 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 | 3,586,385 | |
| -1 | -3,586,385 |
Now, we try dividing 3,586,385 by 3:
3,586,385 ÷ 3 = 1,195,461.6667
If the quotient is a whole number, then 3 and 1,195,461.6667 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 | 3,586,385 | |
| -1 | -3,586,385 |
Let's try dividing by 4:
3,586,385 ÷ 4 = 896,596.25
If the quotient is a whole number, then 4 and 896,596.25 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 | 3,586,385 | |
| -1 | 3,586,385 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 197 | 331 | 985 | 1,655 | 2,167 | 3,641 | 10,835 | 18,205 | 65,207 | 326,035 | 717,277 | 3,586,385 |
| -1 | -5 | -11 | -55 | -197 | -331 | -985 | -1,655 | -2,167 | -3,641 | -10,835 | -18,205 | -65,207 | -326,035 | -717,277 | -3,586,385 |
