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 2,663,297, 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 | 2,663,297 | |
| -1 | -2,663,297 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,663,297.
Example:
1 x 2,663,297 = 2,663,297
and
-1 x -2,663,297 = 2,663,297
Notice both answers equal 2,663,297
With that explanation out of the way, let's continue. Next, we take the number 2,663,297 and divide it by 2:
2,663,297 ÷ 2 = 1,331,648.5
If the quotient is a whole number, then 2 and 1,331,648.5 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 | 2,663,297 | |
| -1 | -2,663,297 |
Now, we try dividing 2,663,297 by 3:
2,663,297 ÷ 3 = 887,765.6667
If the quotient is a whole number, then 3 and 887,765.6667 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 | 2,663,297 | |
| -1 | -2,663,297 |
Let's try dividing by 4:
2,663,297 ÷ 4 = 665,824.25
If the quotient is a whole number, then 4 and 665,824.25 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 | 2,663,297 | |
| -1 | 2,663,297 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 37 | 49 | 91 | 113 | 259 | 481 | 637 | 791 | 1,469 | 1,813 | 3,367 | 4,181 | 5,537 | 10,283 | 23,569 | 29,267 | 54,353 | 71,981 | 204,869 | 380,471 | 2,663,297 |
| -1 | -7 | -13 | -37 | -49 | -91 | -113 | -259 | -481 | -637 | -791 | -1,469 | -1,813 | -3,367 | -4,181 | -5,537 | -10,283 | -23,569 | -29,267 | -54,353 | -71,981 | -204,869 | -380,471 | -2,663,297 |
