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 38,085,595, 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 | 38,085,595 | |
| -1 | -38,085,595 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 38,085,595.
Example:
1 x 38,085,595 = 38,085,595
and
-1 x -38,085,595 = 38,085,595
Notice both answers equal 38,085,595
With that explanation out of the way, let's continue. Next, we take the number 38,085,595 and divide it by 2:
38,085,595 ÷ 2 = 19,042,797.5
If the quotient is a whole number, then 2 and 19,042,797.5 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 | 38,085,595 | |
| -1 | -38,085,595 |
Now, we try dividing 38,085,595 by 3:
38,085,595 ÷ 3 = 12,695,198.3333
If the quotient is a whole number, then 3 and 12,695,198.3333 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 | 38,085,595 | |
| -1 | -38,085,595 |
Let's try dividing by 4:
38,085,595 ÷ 4 = 9,521,398.75
If the quotient is a whole number, then 4 and 9,521,398.75 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 | 38,085,595 | |
| -1 | 38,085,595 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 97 | 485 | 1,843 | 4,133 | 9,215 | 20,665 | 78,527 | 392,635 | 400,901 | 2,004,505 | 7,617,119 | 38,085,595 |
| -1 | -5 | -19 | -95 | -97 | -485 | -1,843 | -4,133 | -9,215 | -20,665 | -78,527 | -392,635 | -400,901 | -2,004,505 | -7,617,119 | -38,085,595 |
