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 1,297,373, 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 | 1,297,373 | |
| -1 | -1,297,373 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,297,373.
Example:
1 x 1,297,373 = 1,297,373
and
-1 x -1,297,373 = 1,297,373
Notice both answers equal 1,297,373
With that explanation out of the way, let's continue. Next, we take the number 1,297,373 and divide it by 2:
1,297,373 ÷ 2 = 648,686.5
If the quotient is a whole number, then 2 and 648,686.5 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 | 1,297,373 | |
| -1 | -1,297,373 |
Now, we try dividing 1,297,373 by 3:
1,297,373 ÷ 3 = 432,457.6667
If the quotient is a whole number, then 3 and 432,457.6667 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 | 1,297,373 | |
| -1 | -1,297,373 |
Let's try dividing by 4:
1,297,373 ÷ 4 = 324,343.25
If the quotient is a whole number, then 4 and 324,343.25 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 | 1,297,373 | |
| -1 | 1,297,373 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 29 | 49 | 77 | 83 | 203 | 319 | 539 | 581 | 913 | 1,421 | 2,233 | 2,407 | 4,067 | 6,391 | 15,631 | 16,849 | 26,477 | 44,737 | 117,943 | 185,339 | 1,297,373 |
| -1 | -7 | -11 | -29 | -49 | -77 | -83 | -203 | -319 | -539 | -581 | -913 | -1,421 | -2,233 | -2,407 | -4,067 | -6,391 | -15,631 | -16,849 | -26,477 | -44,737 | -117,943 | -185,339 | -1,297,373 |
