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 3,205,475, 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 | 3,205,475 | |
| -1 | -3,205,475 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,205,475.
Example:
1 x 3,205,475 = 3,205,475
and
-1 x -3,205,475 = 3,205,475
Notice both answers equal 3,205,475
With that explanation out of the way, let's continue. Next, we take the number 3,205,475 and divide it by 2:
3,205,475 ÷ 2 = 1,602,737.5
If the quotient is a whole number, then 2 and 1,602,737.5 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 | 3,205,475 | |
| -1 | -3,205,475 |
Now, we try dividing 3,205,475 by 3:
3,205,475 ÷ 3 = 1,068,491.6667
If the quotient is a whole number, then 3 and 1,068,491.6667 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 | 3,205,475 | |
| -1 | -3,205,475 |
Let's try dividing by 4:
3,205,475 ÷ 4 = 801,368.75
If the quotient is a whole number, then 4 and 801,368.75 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 | 3,205,475 | |
| -1 | 3,205,475 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 25 | 35 | 65 | 91 | 175 | 325 | 455 | 1,409 | 2,275 | 7,045 | 9,863 | 18,317 | 35,225 | 49,315 | 91,585 | 128,219 | 246,575 | 457,925 | 641,095 | 3,205,475 |
| -1 | -5 | -7 | -13 | -25 | -35 | -65 | -91 | -175 | -325 | -455 | -1,409 | -2,275 | -7,045 | -9,863 | -18,317 | -35,225 | -49,315 | -91,585 | -128,219 | -246,575 | -457,925 | -641,095 | -3,205,475 |
