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 2,409,869, 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 | 2,409,869 | |
| -1 | -2,409,869 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,409,869.
Example:
1 x 2,409,869 = 2,409,869
and
-1 x -2,409,869 = 2,409,869
Notice both answers equal 2,409,869
With that explanation out of the way, let's continue. Next, we take the number 2,409,869 and divide it by 2:
2,409,869 ÷ 2 = 1,204,934.5
If the quotient is a whole number, then 2 and 1,204,934.5 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 | 2,409,869 | |
| -1 | -2,409,869 |
Now, we try dividing 2,409,869 by 3:
2,409,869 ÷ 3 = 803,289.6667
If the quotient is a whole number, then 3 and 803,289.6667 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 | 2,409,869 | |
| -1 | -2,409,869 |
Let's try dividing by 4:
2,409,869 ÷ 4 = 602,467.25
If the quotient is a whole number, then 4 and 602,467.25 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 | 2,409,869 | |
| -1 | 2,409,869 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 17 | 49 | 77 | 119 | 187 | 263 | 539 | 833 | 1,309 | 1,841 | 2,893 | 4,471 | 9,163 | 12,887 | 20,251 | 31,297 | 49,181 | 141,757 | 219,079 | 344,267 | 2,409,869 |
| -1 | -7 | -11 | -17 | -49 | -77 | -119 | -187 | -263 | -539 | -833 | -1,309 | -1,841 | -2,893 | -4,471 | -9,163 | -12,887 | -20,251 | -31,297 | -49,181 | -141,757 | -219,079 | -344,267 | -2,409,869 |
