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 38,528,069, 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 | 38,528,069 | |
| -1 | -38,528,069 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 38,528,069.
Example:
1 x 38,528,069 = 38,528,069
and
-1 x -38,528,069 = 38,528,069
Notice both answers equal 38,528,069
With that explanation out of the way, let's continue. Next, we take the number 38,528,069 and divide it by 2:
38,528,069 ÷ 2 = 19,264,034.5
If the quotient is a whole number, then 2 and 19,264,034.5 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 | 38,528,069 | |
| -1 | -38,528,069 |
Now, we try dividing 38,528,069 by 3:
38,528,069 ÷ 3 = 12,842,689.6667
If the quotient is a whole number, then 3 and 12,842,689.6667 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 | 38,528,069 | |
| -1 | -38,528,069 |
Let's try dividing by 4:
38,528,069 ÷ 4 = 9,632,017.25
If the quotient is a whole number, then 4 and 9,632,017.25 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 | 38,528,069 | |
| -1 | 38,528,069 |
If you did it right, you will end up with this table:
| 1 | 17 | 41 | 167 | 331 | 697 | 2,839 | 5,627 | 6,847 | 13,571 | 55,277 | 116,399 | 230,707 | 939,709 | 2,266,357 | 38,528,069 |
| -1 | -17 | -41 | -167 | -331 | -697 | -2,839 | -5,627 | -6,847 | -13,571 | -55,277 | -116,399 | -230,707 | -939,709 | -2,266,357 | -38,528,069 |
