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 37,408,415, 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 | 37,408,415 | |
| -1 | -37,408,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 37,408,415.
Example:
1 x 37,408,415 = 37,408,415
and
-1 x -37,408,415 = 37,408,415
Notice both answers equal 37,408,415
With that explanation out of the way, let's continue. Next, we take the number 37,408,415 and divide it by 2:
37,408,415 ÷ 2 = 18,704,207.5
If the quotient is a whole number, then 2 and 18,704,207.5 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 | 37,408,415 | |
| -1 | -37,408,415 |
Now, we try dividing 37,408,415 by 3:
37,408,415 ÷ 3 = 12,469,471.6667
If the quotient is a whole number, then 3 and 12,469,471.6667 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 | 37,408,415 | |
| -1 | -37,408,415 |
Let's try dividing by 4:
37,408,415 ÷ 4 = 9,352,103.75
If the quotient is a whole number, then 4 and 9,352,103.75 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 | 37,408,415 | |
| -1 | 37,408,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 17 | 55 | 85 | 187 | 935 | 40,009 | 200,045 | 440,099 | 680,153 | 2,200,495 | 3,400,765 | 7,481,683 | 37,408,415 |
| -1 | -5 | -11 | -17 | -55 | -85 | -187 | -935 | -40,009 | -200,045 | -440,099 | -680,153 | -2,200,495 | -3,400,765 | -7,481,683 | -37,408,415 |
