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 38,853,595, 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 | 38,853,595 | |
| -1 | -38,853,595 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 38,853,595.
Example:
1 x 38,853,595 = 38,853,595
and
-1 x -38,853,595 = 38,853,595
Notice both answers equal 38,853,595
With that explanation out of the way, let's continue. Next, we take the number 38,853,595 and divide it by 2:
38,853,595 ÷ 2 = 19,426,797.5
If the quotient is a whole number, then 2 and 19,426,797.5 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 | 38,853,595 | |
| -1 | -38,853,595 |
Now, we try dividing 38,853,595 by 3:
38,853,595 ÷ 3 = 12,951,198.3333
If the quotient is a whole number, then 3 and 12,951,198.3333 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 | 38,853,595 | |
| -1 | -38,853,595 |
Let's try dividing by 4:
38,853,595 ÷ 4 = 9,713,398.75
If the quotient is a whole number, then 4 and 9,713,398.75 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 | 38,853,595 | |
| -1 | 38,853,595 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 109 | 545 | 1,199 | 5,995 | 6,481 | 32,405 | 71,291 | 356,455 | 706,429 | 3,532,145 | 7,770,719 | 38,853,595 |
| -1 | -5 | -11 | -55 | -109 | -545 | -1,199 | -5,995 | -6,481 | -32,405 | -71,291 | -356,455 | -706,429 | -3,532,145 | -7,770,719 | -38,853,595 |
