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 37,904,009, 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 | 37,904,009 | |
| -1 | -37,904,009 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 37,904,009.
Example:
1 x 37,904,009 = 37,904,009
and
-1 x -37,904,009 = 37,904,009
Notice both answers equal 37,904,009
With that explanation out of the way, let's continue. Next, we take the number 37,904,009 and divide it by 2:
37,904,009 ÷ 2 = 18,952,004.5
If the quotient is a whole number, then 2 and 18,952,004.5 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 | 37,904,009 | |
| -1 | -37,904,009 |
Now, we try dividing 37,904,009 by 3:
37,904,009 ÷ 3 = 12,634,669.6667
If the quotient is a whole number, then 3 and 12,634,669.6667 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 | 37,904,009 | |
| -1 | -37,904,009 |
Let's try dividing by 4:
37,904,009 ÷ 4 = 9,476,002.25
If the quotient is a whole number, then 4 and 9,476,002.25 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 | 37,904,009 | |
| -1 | 37,904,009 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 73 | 143 | 803 | 949 | 3,631 | 10,439 | 39,941 | 47,203 | 265,063 | 519,233 | 2,915,693 | 3,445,819 | 37,904,009 |
| -1 | -11 | -13 | -73 | -143 | -803 | -949 | -3,631 | -10,439 | -39,941 | -47,203 | -265,063 | -519,233 | -2,915,693 | -3,445,819 | -37,904,009 |
