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 13,413,565, 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 | 13,413,565 | |
| -1 | -13,413,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,413,565.
Example:
1 x 13,413,565 = 13,413,565
and
-1 x -13,413,565 = 13,413,565
Notice both answers equal 13,413,565
With that explanation out of the way, let's continue. Next, we take the number 13,413,565 and divide it by 2:
13,413,565 ÷ 2 = 6,706,782.5
If the quotient is a whole number, then 2 and 6,706,782.5 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 | 13,413,565 | |
| -1 | -13,413,565 |
Now, we try dividing 13,413,565 by 3:
13,413,565 ÷ 3 = 4,471,188.3333
If the quotient is a whole number, then 3 and 4,471,188.3333 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 | 13,413,565 | |
| -1 | -13,413,565 |
Let's try dividing by 4:
13,413,565 ÷ 4 = 3,353,391.25
If the quotient is a whole number, then 4 and 3,353,391.25 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 | 13,413,565 | |
| -1 | 13,413,565 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 47 | 55 | 235 | 517 | 2,585 | 5,189 | 25,945 | 57,079 | 243,883 | 285,395 | 1,219,415 | 2,682,713 | 13,413,565 |
| -1 | -5 | -11 | -47 | -55 | -235 | -517 | -2,585 | -5,189 | -25,945 | -57,079 | -243,883 | -285,395 | -1,219,415 | -2,682,713 | -13,413,565 |
