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 104,031,145, 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 | 104,031,145 | |
| -1 | -104,031,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 104,031,145.
Example:
1 x 104,031,145 = 104,031,145
and
-1 x -104,031,145 = 104,031,145
Notice both answers equal 104,031,145
With that explanation out of the way, let's continue. Next, we take the number 104,031,145 and divide it by 2:
104,031,145 ÷ 2 = 52,015,572.5
If the quotient is a whole number, then 2 and 52,015,572.5 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 | 104,031,145 | |
| -1 | -104,031,145 |
Now, we try dividing 104,031,145 by 3:
104,031,145 ÷ 3 = 34,677,048.3333
If the quotient is a whole number, then 3 and 34,677,048.3333 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 | 104,031,145 | |
| -1 | -104,031,145 |
Let's try dividing by 4:
104,031,145 ÷ 4 = 26,007,786.25
If the quotient is a whole number, then 4 and 26,007,786.25 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 | 104,031,145 | |
| -1 | 104,031,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 205 | 683 | 743 | 3,415 | 3,715 | 28,003 | 30,463 | 140,015 | 152,315 | 507,469 | 2,537,345 | 20,806,229 | 104,031,145 |
| -1 | -5 | -41 | -205 | -683 | -743 | -3,415 | -3,715 | -28,003 | -30,463 | -140,015 | -152,315 | -507,469 | -2,537,345 | -20,806,229 | -104,031,145 |
