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 3,413,315, 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 | 3,413,315 | |
| -1 | -3,413,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,413,315.
Example:
1 x 3,413,315 = 3,413,315
and
-1 x -3,413,315 = 3,413,315
Notice both answers equal 3,413,315
With that explanation out of the way, let's continue. Next, we take the number 3,413,315 and divide it by 2:
3,413,315 ÷ 2 = 1,706,657.5
If the quotient is a whole number, then 2 and 1,706,657.5 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 | 3,413,315 | |
| -1 | -3,413,315 |
Now, we try dividing 3,413,315 by 3:
3,413,315 ÷ 3 = 1,137,771.6667
If the quotient is a whole number, then 3 and 1,137,771.6667 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 | 3,413,315 | |
| -1 | -3,413,315 |
Let's try dividing by 4:
3,413,315 ÷ 4 = 853,328.75
If the quotient is a whole number, then 4 and 853,328.75 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 | 3,413,315 | |
| -1 | 3,413,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 67 | 115 | 335 | 443 | 1,541 | 2,215 | 7,705 | 10,189 | 29,681 | 50,945 | 148,405 | 682,663 | 3,413,315 |
| -1 | -5 | -23 | -67 | -115 | -335 | -443 | -1,541 | -2,215 | -7,705 | -10,189 | -29,681 | -50,945 | -148,405 | -682,663 | -3,413,315 |
