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 3,088,561, 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 | 3,088,561 | |
| -1 | -3,088,561 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,088,561.
Example:
1 x 3,088,561 = 3,088,561
and
-1 x -3,088,561 = 3,088,561
Notice both answers equal 3,088,561
With that explanation out of the way, let's continue. Next, we take the number 3,088,561 and divide it by 2:
3,088,561 ÷ 2 = 1,544,280.5
If the quotient is a whole number, then 2 and 1,544,280.5 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 | 3,088,561 | |
| -1 | -3,088,561 |
Now, we try dividing 3,088,561 by 3:
3,088,561 ÷ 3 = 1,029,520.3333
If the quotient is a whole number, then 3 and 1,029,520.3333 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 | 3,088,561 | |
| -1 | -3,088,561 |
Let's try dividing by 4:
3,088,561 ÷ 4 = 772,140.25
If the quotient is a whole number, then 4 and 772,140.25 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 | 3,088,561 | |
| -1 | 3,088,561 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 43 | 217 | 301 | 331 | 1,333 | 2,317 | 9,331 | 10,261 | 14,233 | 71,827 | 99,631 | 441,223 | 3,088,561 |
| -1 | -7 | -31 | -43 | -217 | -301 | -331 | -1,333 | -2,317 | -9,331 | -10,261 | -14,233 | -71,827 | -99,631 | -441,223 | -3,088,561 |
