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 3,520,205, 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 | 3,520,205 | |
| -1 | -3,520,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,520,205.
Example:
1 x 3,520,205 = 3,520,205
and
-1 x -3,520,205 = 3,520,205
Notice both answers equal 3,520,205
With that explanation out of the way, let's continue. Next, we take the number 3,520,205 and divide it by 2:
3,520,205 ÷ 2 = 1,760,102.5
If the quotient is a whole number, then 2 and 1,760,102.5 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 | 3,520,205 | |
| -1 | -3,520,205 |
Now, we try dividing 3,520,205 by 3:
3,520,205 ÷ 3 = 1,173,401.6667
If the quotient is a whole number, then 3 and 1,173,401.6667 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 | 3,520,205 | |
| -1 | -3,520,205 |
Let's try dividing by 4:
3,520,205 ÷ 4 = 880,051.25
If the quotient is a whole number, then 4 and 880,051.25 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 | 3,520,205 | |
| -1 | 3,520,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 31 | 65 | 155 | 403 | 1,747 | 2,015 | 8,735 | 22,711 | 54,157 | 113,555 | 270,785 | 704,041 | 3,520,205 |
| -1 | -5 | -13 | -31 | -65 | -155 | -403 | -1,747 | -2,015 | -8,735 | -22,711 | -54,157 | -113,555 | -270,785 | -704,041 | -3,520,205 |
