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 5,209,339, 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 | 5,209,339 | |
| -1 | -5,209,339 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,209,339.
Example:
1 x 5,209,339 = 5,209,339
and
-1 x -5,209,339 = 5,209,339
Notice both answers equal 5,209,339
With that explanation out of the way, let's continue. Next, we take the number 5,209,339 and divide it by 2:
5,209,339 ÷ 2 = 2,604,669.5
If the quotient is a whole number, then 2 and 2,604,669.5 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 | 5,209,339 | |
| -1 | -5,209,339 |
Now, we try dividing 5,209,339 by 3:
5,209,339 ÷ 3 = 1,736,446.3333
If the quotient is a whole number, then 3 and 1,736,446.3333 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 | 5,209,339 | |
| -1 | -5,209,339 |
Let's try dividing by 4:
5,209,339 ÷ 4 = 1,302,334.75
If the quotient is a whole number, then 4 and 1,302,334.75 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 | 5,209,339 | |
| -1 | 5,209,339 |
If you did it right, you will end up with this table:
| 1 | 23 | 47 | 61 | 79 | 1,081 | 1,403 | 1,817 | 2,867 | 3,713 | 4,819 | 65,941 | 85,399 | 110,837 | 226,493 | 5,209,339 |
| -1 | -23 | -47 | -61 | -79 | -1,081 | -1,403 | -1,817 | -2,867 | -3,713 | -4,819 | -65,941 | -85,399 | -110,837 | -226,493 | -5,209,339 |
