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 38,208,335, 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 | 38,208,335 | |
| -1 | -38,208,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 38,208,335.
Example:
1 x 38,208,335 = 38,208,335
and
-1 x -38,208,335 = 38,208,335
Notice both answers equal 38,208,335
With that explanation out of the way, let's continue. Next, we take the number 38,208,335 and divide it by 2:
38,208,335 ÷ 2 = 19,104,167.5
If the quotient is a whole number, then 2 and 19,104,167.5 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 | 38,208,335 | |
| -1 | -38,208,335 |
Now, we try dividing 38,208,335 by 3:
38,208,335 ÷ 3 = 12,736,111.6667
If the quotient is a whole number, then 3 and 12,736,111.6667 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 | 38,208,335 | |
| -1 | -38,208,335 |
Let's try dividing by 4:
38,208,335 ÷ 4 = 9,552,083.75
If the quotient is a whole number, then 4 and 9,552,083.75 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 | 38,208,335 | |
| -1 | 38,208,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 19 | 55 | 95 | 209 | 1,045 | 36,563 | 182,815 | 402,193 | 694,697 | 2,010,965 | 3,473,485 | 7,641,667 | 38,208,335 |
| -1 | -5 | -11 | -19 | -55 | -95 | -209 | -1,045 | -36,563 | -182,815 | -402,193 | -694,697 | -2,010,965 | -3,473,485 | -7,641,667 | -38,208,335 |
