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 5,155,709, 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 | 5,155,709 | |
| -1 | -5,155,709 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,155,709.
Example:
1 x 5,155,709 = 5,155,709
and
-1 x -5,155,709 = 5,155,709
Notice both answers equal 5,155,709
With that explanation out of the way, let's continue. Next, we take the number 5,155,709 and divide it by 2:
5,155,709 ÷ 2 = 2,577,854.5
If the quotient is a whole number, then 2 and 2,577,854.5 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 | 5,155,709 | |
| -1 | -5,155,709 |
Now, we try dividing 5,155,709 by 3:
5,155,709 ÷ 3 = 1,718,569.6667
If the quotient is a whole number, then 3 and 1,718,569.6667 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 | 5,155,709 | |
| -1 | -5,155,709 |
Let's try dividing by 4:
5,155,709 ÷ 4 = 1,288,927.25
If the quotient is a whole number, then 4 and 1,288,927.25 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 | 5,155,709 | |
| -1 | 5,155,709 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 41 | 221 | 533 | 569 | 697 | 7,397 | 9,061 | 9,673 | 23,329 | 125,749 | 303,277 | 396,593 | 5,155,709 |
| -1 | -13 | -17 | -41 | -221 | -533 | -569 | -697 | -7,397 | -9,061 | -9,673 | -23,329 | -125,749 | -303,277 | -396,593 | -5,155,709 |
