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 38,355,623, 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 | 38,355,623 | |
| -1 | -38,355,623 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 38,355,623.
Example:
1 x 38,355,623 = 38,355,623
and
-1 x -38,355,623 = 38,355,623
Notice both answers equal 38,355,623
With that explanation out of the way, let's continue. Next, we take the number 38,355,623 and divide it by 2:
38,355,623 ÷ 2 = 19,177,811.5
If the quotient is a whole number, then 2 and 19,177,811.5 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 | 38,355,623 | |
| -1 | -38,355,623 |
Now, we try dividing 38,355,623 by 3:
38,355,623 ÷ 3 = 12,785,207.6667
If the quotient is a whole number, then 3 and 12,785,207.6667 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 | 38,355,623 | |
| -1 | -38,355,623 |
Let's try dividing by 4:
38,355,623 ÷ 4 = 9,588,905.75
If the quotient is a whole number, then 4 and 9,588,905.75 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 | 38,355,623 | |
| -1 | 38,355,623 |
If you did it right, you will end up with this table:
| 1 | 19 | 41 | 53 | 779 | 929 | 1,007 | 2,173 | 17,651 | 38,089 | 41,287 | 49,237 | 723,691 | 935,503 | 2,018,717 | 38,355,623 |
| -1 | -19 | -41 | -53 | -779 | -929 | -1,007 | -2,173 | -17,651 | -38,089 | -41,287 | -49,237 | -723,691 | -935,503 | -2,018,717 | -38,355,623 |
