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 3,489,605, 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 | 3,489,605 | |
| -1 | -3,489,605 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,489,605.
Example:
1 x 3,489,605 = 3,489,605
and
-1 x -3,489,605 = 3,489,605
Notice both answers equal 3,489,605
With that explanation out of the way, let's continue. Next, we take the number 3,489,605 and divide it by 2:
3,489,605 ÷ 2 = 1,744,802.5
If the quotient is a whole number, then 2 and 1,744,802.5 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 | 3,489,605 | |
| -1 | -3,489,605 |
Now, we try dividing 3,489,605 by 3:
3,489,605 ÷ 3 = 1,163,201.6667
If the quotient is a whole number, then 3 and 1,163,201.6667 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 | 3,489,605 | |
| -1 | -3,489,605 |
Let's try dividing by 4:
3,489,605 ÷ 4 = 872,401.25
If the quotient is a whole number, then 4 and 872,401.25 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 | 3,489,605 | |
| -1 | 3,489,605 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 179 | 557 | 895 | 1,253 | 2,785 | 3,899 | 6,265 | 19,495 | 99,703 | 498,515 | 697,921 | 3,489,605 |
| -1 | -5 | -7 | -35 | -179 | -557 | -895 | -1,253 | -2,785 | -3,899 | -6,265 | -19,495 | -99,703 | -498,515 | -697,921 | -3,489,605 |
