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 108,571,603, 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 | 108,571,603 | |
| -1 | -108,571,603 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 108,571,603.
Example:
1 x 108,571,603 = 108,571,603
and
-1 x -108,571,603 = 108,571,603
Notice both answers equal 108,571,603
With that explanation out of the way, let's continue. Next, we take the number 108,571,603 and divide it by 2:
108,571,603 ÷ 2 = 54,285,801.5
If the quotient is a whole number, then 2 and 54,285,801.5 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 | 108,571,603 | |
| -1 | -108,571,603 |
Now, we try dividing 108,571,603 by 3:
108,571,603 ÷ 3 = 36,190,534.3333
If the quotient is a whole number, then 3 and 36,190,534.3333 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 | 108,571,603 | |
| -1 | -108,571,603 |
Let's try dividing by 4:
108,571,603 ÷ 4 = 27,142,900.75
If the quotient is a whole number, then 4 and 27,142,900.75 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 | 108,571,603 | |
| -1 | 108,571,603 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 49 | 227 | 301 | 1,589 | 2,107 | 9,761 | 11,123 | 51,529 | 68,327 | 360,703 | 478,289 | 2,215,747 | 2,524,921 | 15,510,229 | 108,571,603 |
| -1 | -7 | -43 | -49 | -227 | -301 | -1,589 | -2,107 | -9,761 | -11,123 | -51,529 | -68,327 | -360,703 | -478,289 | -2,215,747 | -2,524,921 | -15,510,229 | -108,571,603 |
