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 38,004,707, 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 | 38,004,707 | |
| -1 | -38,004,707 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 38,004,707.
Example:
1 x 38,004,707 = 38,004,707
and
-1 x -38,004,707 = 38,004,707
Notice both answers equal 38,004,707
With that explanation out of the way, let's continue. Next, we take the number 38,004,707 and divide it by 2:
38,004,707 ÷ 2 = 19,002,353.5
If the quotient is a whole number, then 2 and 19,002,353.5 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 | 38,004,707 | |
| -1 | -38,004,707 |
Now, we try dividing 38,004,707 by 3:
38,004,707 ÷ 3 = 12,668,235.6667
If the quotient is a whole number, then 3 and 12,668,235.6667 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 | 38,004,707 | |
| -1 | -38,004,707 |
Let's try dividing by 4:
38,004,707 ÷ 4 = 9,501,176.75
If the quotient is a whole number, then 4 and 9,501,176.75 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 | 38,004,707 | |
| -1 | 38,004,707 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 221 | 383 | 449 | 4,979 | 5,837 | 6,511 | 7,633 | 84,643 | 99,229 | 171,967 | 2,235,571 | 2,923,439 | 38,004,707 |
| -1 | -13 | -17 | -221 | -383 | -449 | -4,979 | -5,837 | -6,511 | -7,633 | -84,643 | -99,229 | -171,967 | -2,235,571 | -2,923,439 | -38,004,707 |
