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 1,297,009, 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 | 1,297,009 | |
| -1 | -1,297,009 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,297,009.
Example:
1 x 1,297,009 = 1,297,009
and
-1 x -1,297,009 = 1,297,009
Notice both answers equal 1,297,009
With that explanation out of the way, let's continue. Next, we take the number 1,297,009 and divide it by 2:
1,297,009 ÷ 2 = 648,504.5
If the quotient is a whole number, then 2 and 648,504.5 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 | 1,297,009 | |
| -1 | -1,297,009 |
Now, we try dividing 1,297,009 by 3:
1,297,009 ÷ 3 = 432,336.3333
If the quotient is a whole number, then 3 and 432,336.3333 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 | 1,297,009 | |
| -1 | -1,297,009 |
Let's try dividing by 4:
1,297,009 ÷ 4 = 324,252.25
If the quotient is a whole number, then 4 and 324,252.25 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 | 1,297,009 | |
| -1 | 1,297,009 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 43 | 139 | 217 | 301 | 973 | 1,333 | 4,309 | 5,977 | 9,331 | 30,163 | 41,839 | 185,287 | 1,297,009 |
| -1 | -7 | -31 | -43 | -139 | -217 | -301 | -973 | -1,333 | -4,309 | -5,977 | -9,331 | -30,163 | -41,839 | -185,287 | -1,297,009 |
