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 2,809,499, 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 | 2,809,499 | |
| -1 | -2,809,499 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,809,499.
Example:
1 x 2,809,499 = 2,809,499
and
-1 x -2,809,499 = 2,809,499
Notice both answers equal 2,809,499
With that explanation out of the way, let's continue. Next, we take the number 2,809,499 and divide it by 2:
2,809,499 ÷ 2 = 1,404,749.5
If the quotient is a whole number, then 2 and 1,404,749.5 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 | 2,809,499 | |
| -1 | -2,809,499 |
Now, we try dividing 2,809,499 by 3:
2,809,499 ÷ 3 = 936,499.6667
If the quotient is a whole number, then 3 and 936,499.6667 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 | 2,809,499 | |
| -1 | -2,809,499 |
Let's try dividing by 4:
2,809,499 ÷ 4 = 702,374.75
If the quotient is a whole number, then 4 and 702,374.75 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 | 2,809,499 | |
| -1 | 2,809,499 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 31 | 77 | 107 | 121 | 217 | 341 | 749 | 847 | 1,177 | 2,387 | 3,317 | 3,751 | 8,239 | 12,947 | 23,219 | 26,257 | 36,487 | 90,629 | 255,409 | 401,357 | 2,809,499 |
| -1 | -7 | -11 | -31 | -77 | -107 | -121 | -217 | -341 | -749 | -847 | -1,177 | -2,387 | -3,317 | -3,751 | -8,239 | -12,947 | -23,219 | -26,257 | -36,487 | -90,629 | -255,409 | -401,357 | -2,809,499 |
