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 15,359,357, 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 | 15,359,357 | |
| -1 | -15,359,357 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,359,357.
Example:
1 x 15,359,357 = 15,359,357
and
-1 x -15,359,357 = 15,359,357
Notice both answers equal 15,359,357
With that explanation out of the way, let's continue. Next, we take the number 15,359,357 and divide it by 2:
15,359,357 ÷ 2 = 7,679,678.5
If the quotient is a whole number, then 2 and 7,679,678.5 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 | 15,359,357 | |
| -1 | -15,359,357 |
Now, we try dividing 15,359,357 by 3:
15,359,357 ÷ 3 = 5,119,785.6667
If the quotient is a whole number, then 3 and 5,119,785.6667 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 | 15,359,357 | |
| -1 | -15,359,357 |
Let's try dividing by 4:
15,359,357 ÷ 4 = 3,839,839.25
If the quotient is a whole number, then 4 and 3,839,839.25 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 | 15,359,357 | |
| -1 | 15,359,357 |
If you did it right, you will end up with this table:
| 1 | 13 | 29 | 131 | 311 | 377 | 1,703 | 3,799 | 4,043 | 9,019 | 40,741 | 49,387 | 117,247 | 529,633 | 1,181,489 | 15,359,357 |
| -1 | -13 | -29 | -131 | -311 | -377 | -1,703 | -3,799 | -4,043 | -9,019 | -40,741 | -49,387 | -117,247 | -529,633 | -1,181,489 | -15,359,357 |
