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 15,675,055, 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 | 15,675,055 | |
| -1 | -15,675,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,675,055.
Example:
1 x 15,675,055 = 15,675,055
and
-1 x -15,675,055 = 15,675,055
Notice both answers equal 15,675,055
With that explanation out of the way, let's continue. Next, we take the number 15,675,055 and divide it by 2:
15,675,055 ÷ 2 = 7,837,527.5
If the quotient is a whole number, then 2 and 7,837,527.5 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 | 15,675,055 | |
| -1 | -15,675,055 |
Now, we try dividing 15,675,055 by 3:
15,675,055 ÷ 3 = 5,225,018.3333
If the quotient is a whole number, then 3 and 5,225,018.3333 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 | 15,675,055 | |
| -1 | -15,675,055 |
Let's try dividing by 4:
15,675,055 ÷ 4 = 3,918,763.75
If the quotient is a whole number, then 4 and 3,918,763.75 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 | 15,675,055 | |
| -1 | 15,675,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 103 | 515 | 1,133 | 2,767 | 5,665 | 13,835 | 30,437 | 152,185 | 285,001 | 1,425,005 | 3,135,011 | 15,675,055 |
| -1 | -5 | -11 | -55 | -103 | -515 | -1,133 | -2,767 | -5,665 | -13,835 | -30,437 | -152,185 | -285,001 | -1,425,005 | -3,135,011 | -15,675,055 |
