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 3,088,813, 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 | 3,088,813 | |
| -1 | -3,088,813 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,088,813.
Example:
1 x 3,088,813 = 3,088,813
and
-1 x -3,088,813 = 3,088,813
Notice both answers equal 3,088,813
With that explanation out of the way, let's continue. Next, we take the number 3,088,813 and divide it by 2:
3,088,813 ÷ 2 = 1,544,406.5
If the quotient is a whole number, then 2 and 1,544,406.5 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 | 3,088,813 | |
| -1 | -3,088,813 |
Now, we try dividing 3,088,813 by 3:
3,088,813 ÷ 3 = 1,029,604.3333
If the quotient is a whole number, then 3 and 1,029,604.3333 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 | 3,088,813 | |
| -1 | -3,088,813 |
Let's try dividing by 4:
3,088,813 ÷ 4 = 772,203.25
If the quotient is a whole number, then 4 and 772,203.25 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 | 3,088,813 | |
| -1 | 3,088,813 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 49 | 91 | 169 | 373 | 637 | 1,183 | 2,611 | 4,849 | 8,281 | 18,277 | 33,943 | 63,037 | 237,601 | 441,259 | 3,088,813 |
| -1 | -7 | -13 | -49 | -91 | -169 | -373 | -637 | -1,183 | -2,611 | -4,849 | -8,281 | -18,277 | -33,943 | -63,037 | -237,601 | -441,259 | -3,088,813 |
