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 37,707,439, 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 | 37,707,439 | |
| -1 | -37,707,439 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 37,707,439.
Example:
1 x 37,707,439 = 37,707,439
and
-1 x -37,707,439 = 37,707,439
Notice both answers equal 37,707,439
With that explanation out of the way, let's continue. Next, we take the number 37,707,439 and divide it by 2:
37,707,439 ÷ 2 = 18,853,719.5
If the quotient is a whole number, then 2 and 18,853,719.5 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 | 37,707,439 | |
| -1 | -37,707,439 |
Now, we try dividing 37,707,439 by 3:
37,707,439 ÷ 3 = 12,569,146.3333
If the quotient is a whole number, then 3 and 12,569,146.3333 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 | 37,707,439 | |
| -1 | -37,707,439 |
Let's try dividing by 4:
37,707,439 ÷ 4 = 9,426,859.75
If the quotient is a whole number, then 4 and 9,426,859.75 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 | 37,707,439 | |
| -1 | 37,707,439 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 31 | 77 | 217 | 341 | 2,387 | 15,797 | 110,579 | 173,767 | 489,707 | 1,216,369 | 3,427,949 | 5,386,777 | 37,707,439 |
| -1 | -7 | -11 | -31 | -77 | -217 | -341 | -2,387 | -15,797 | -110,579 | -173,767 | -489,707 | -1,216,369 | -3,427,949 | -5,386,777 | -37,707,439 |
