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 38,170,223, 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 | 38,170,223 | |
| -1 | -38,170,223 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 38,170,223.
Example:
1 x 38,170,223 = 38,170,223
and
-1 x -38,170,223 = 38,170,223
Notice both answers equal 38,170,223
With that explanation out of the way, let's continue. Next, we take the number 38,170,223 and divide it by 2:
38,170,223 ÷ 2 = 19,085,111.5
If the quotient is a whole number, then 2 and 19,085,111.5 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 | 38,170,223 | |
| -1 | -38,170,223 |
Now, we try dividing 38,170,223 by 3:
38,170,223 ÷ 3 = 12,723,407.6667
If the quotient is a whole number, then 3 and 12,723,407.6667 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 | 38,170,223 | |
| -1 | -38,170,223 |
Let's try dividing by 4:
38,170,223 ÷ 4 = 9,542,555.75
If the quotient is a whole number, then 4 and 9,542,555.75 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 | 38,170,223 | |
| -1 | 38,170,223 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 101 | 707 | 1,313 | 4,153 | 9,191 | 29,071 | 53,989 | 377,923 | 419,453 | 2,936,171 | 5,452,889 | 38,170,223 |
| -1 | -7 | -13 | -91 | -101 | -707 | -1,313 | -4,153 | -9,191 | -29,071 | -53,989 | -377,923 | -419,453 | -2,936,171 | -5,452,889 | -38,170,223 |
