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 3,040,555, 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 | 3,040,555 | |
| -1 | -3,040,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,040,555.
Example:
1 x 3,040,555 = 3,040,555
and
-1 x -3,040,555 = 3,040,555
Notice both answers equal 3,040,555
With that explanation out of the way, let's continue. Next, we take the number 3,040,555 and divide it by 2:
3,040,555 ÷ 2 = 1,520,277.5
If the quotient is a whole number, then 2 and 1,520,277.5 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 | 3,040,555 | |
| -1 | -3,040,555 |
Now, we try dividing 3,040,555 by 3:
3,040,555 ÷ 3 = 1,013,518.3333
If the quotient is a whole number, then 3 and 1,013,518.3333 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 | 3,040,555 | |
| -1 | -3,040,555 |
Let's try dividing by 4:
3,040,555 ÷ 4 = 760,138.75
If the quotient is a whole number, then 4 and 760,138.75 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 | 3,040,555 | |
| -1 | 3,040,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 109 | 545 | 763 | 797 | 3,815 | 3,985 | 5,579 | 27,895 | 86,873 | 434,365 | 608,111 | 3,040,555 |
| -1 | -5 | -7 | -35 | -109 | -545 | -763 | -797 | -3,815 | -3,985 | -5,579 | -27,895 | -86,873 | -434,365 | -608,111 | -3,040,555 |
