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 3,029,873, 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 | 3,029,873 | |
| -1 | -3,029,873 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,029,873.
Example:
1 x 3,029,873 = 3,029,873
and
-1 x -3,029,873 = 3,029,873
Notice both answers equal 3,029,873
With that explanation out of the way, let's continue. Next, we take the number 3,029,873 and divide it by 2:
3,029,873 ÷ 2 = 1,514,936.5
If the quotient is a whole number, then 2 and 1,514,936.5 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 | 3,029,873 | |
| -1 | -3,029,873 |
Now, we try dividing 3,029,873 by 3:
3,029,873 ÷ 3 = 1,009,957.6667
If the quotient is a whole number, then 3 and 1,009,957.6667 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 | 3,029,873 | |
| -1 | -3,029,873 |
Let's try dividing by 4:
3,029,873 ÷ 4 = 757,468.25
If the quotient is a whole number, then 4 and 757,468.25 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 | 3,029,873 | |
| -1 | 3,029,873 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 19 | 77 | 109 | 133 | 209 | 361 | 763 | 1,199 | 1,463 | 2,071 | 2,527 | 3,971 | 8,393 | 14,497 | 22,781 | 27,797 | 39,349 | 159,467 | 275,443 | 432,839 | 3,029,873 |
| -1 | -7 | -11 | -19 | -77 | -109 | -133 | -209 | -361 | -763 | -1,199 | -1,463 | -2,071 | -2,527 | -3,971 | -8,393 | -14,497 | -22,781 | -27,797 | -39,349 | -159,467 | -275,443 | -432,839 | -3,029,873 |
