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 103,351,885, 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 | 103,351,885 | |
| -1 | -103,351,885 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,351,885.
Example:
1 x 103,351,885 = 103,351,885
and
-1 x -103,351,885 = 103,351,885
Notice both answers equal 103,351,885
With that explanation out of the way, let's continue. Next, we take the number 103,351,885 and divide it by 2:
103,351,885 ÷ 2 = 51,675,942.5
If the quotient is a whole number, then 2 and 51,675,942.5 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 | 103,351,885 | |
| -1 | -103,351,885 |
Now, we try dividing 103,351,885 by 3:
103,351,885 ÷ 3 = 34,450,628.3333
If the quotient is a whole number, then 3 and 34,450,628.3333 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 | 103,351,885 | |
| -1 | -103,351,885 |
Let's try dividing by 4:
103,351,885 ÷ 4 = 25,837,971.25
If the quotient is a whole number, then 4 and 25,837,971.25 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 | 103,351,885 | |
| -1 | 103,351,885 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 455 | 227,147 | 1,135,735 | 1,590,029 | 2,952,911 | 7,950,145 | 14,764,555 | 20,670,377 | 103,351,885 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -455 | -227,147 | -1,135,735 | -1,590,029 | -2,952,911 | -7,950,145 | -14,764,555 | -20,670,377 | -103,351,885 |
