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 38,524,367, 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 | 38,524,367 | |
| -1 | -38,524,367 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 38,524,367.
Example:
1 x 38,524,367 = 38,524,367
and
-1 x -38,524,367 = 38,524,367
Notice both answers equal 38,524,367
With that explanation out of the way, let's continue. Next, we take the number 38,524,367 and divide it by 2:
38,524,367 ÷ 2 = 19,262,183.5
If the quotient is a whole number, then 2 and 19,262,183.5 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 | 38,524,367 | |
| -1 | -38,524,367 |
Now, we try dividing 38,524,367 by 3:
38,524,367 ÷ 3 = 12,841,455.6667
If the quotient is a whole number, then 3 and 12,841,455.6667 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 | 38,524,367 | |
| -1 | -38,524,367 |
Let's try dividing by 4:
38,524,367 ÷ 4 = 9,631,091.75
If the quotient is a whole number, then 4 and 9,631,091.75 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 | 38,524,367 | |
| -1 | 38,524,367 |
If you did it right, you will end up with this table:
| 1 | 7 | 61 | 83 | 427 | 581 | 1,087 | 5,063 | 7,609 | 35,441 | 66,307 | 90,221 | 464,149 | 631,547 | 5,503,481 | 38,524,367 |
| -1 | -7 | -61 | -83 | -427 | -581 | -1,087 | -5,063 | -7,609 | -35,441 | -66,307 | -90,221 | -464,149 | -631,547 | -5,503,481 | -38,524,367 |
