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 37,373,873, 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 | 37,373,873 | |
| -1 | -37,373,873 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 37,373,873.
Example:
1 x 37,373,873 = 37,373,873
and
-1 x -37,373,873 = 37,373,873
Notice both answers equal 37,373,873
With that explanation out of the way, let's continue. Next, we take the number 37,373,873 and divide it by 2:
37,373,873 ÷ 2 = 18,686,936.5
If the quotient is a whole number, then 2 and 18,686,936.5 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 | 37,373,873 | |
| -1 | -37,373,873 |
Now, we try dividing 37,373,873 by 3:
37,373,873 ÷ 3 = 12,457,957.6667
If the quotient is a whole number, then 3 and 12,457,957.6667 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 | 37,373,873 | |
| -1 | -37,373,873 |
Let's try dividing by 4:
37,373,873 ÷ 4 = 9,343,468.25
If the quotient is a whole number, then 4 and 9,343,468.25 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 | 37,373,873 | |
| -1 | 37,373,873 |
If you did it right, you will end up with this table:
| 1 | 23 | 67 | 79 | 307 | 1,541 | 1,817 | 5,293 | 7,061 | 20,569 | 24,253 | 121,739 | 473,087 | 557,819 | 1,624,951 | 37,373,873 |
| -1 | -23 | -67 | -79 | -307 | -1,541 | -1,817 | -5,293 | -7,061 | -20,569 | -24,253 | -121,739 | -473,087 | -557,819 | -1,624,951 | -37,373,873 |
