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 15,040,325, 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 | 15,040,325 | |
| -1 | -15,040,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,040,325.
Example:
1 x 15,040,325 = 15,040,325
and
-1 x -15,040,325 = 15,040,325
Notice both answers equal 15,040,325
With that explanation out of the way, let's continue. Next, we take the number 15,040,325 and divide it by 2:
15,040,325 ÷ 2 = 7,520,162.5
If the quotient is a whole number, then 2 and 7,520,162.5 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 | 15,040,325 | |
| -1 | -15,040,325 |
Now, we try dividing 15,040,325 by 3:
15,040,325 ÷ 3 = 5,013,441.6667
If the quotient is a whole number, then 3 and 5,013,441.6667 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 | 15,040,325 | |
| -1 | -15,040,325 |
Let's try dividing by 4:
15,040,325 ÷ 4 = 3,760,081.25
If the quotient is a whole number, then 4 and 3,760,081.25 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 | 15,040,325 | |
| -1 | 15,040,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 43 | 85 | 215 | 425 | 731 | 823 | 1,075 | 3,655 | 4,115 | 13,991 | 18,275 | 20,575 | 35,389 | 69,955 | 176,945 | 349,775 | 601,613 | 884,725 | 3,008,065 | 15,040,325 |
| -1 | -5 | -17 | -25 | -43 | -85 | -215 | -425 | -731 | -823 | -1,075 | -3,655 | -4,115 | -13,991 | -18,275 | -20,575 | -35,389 | -69,955 | -176,945 | -349,775 | -601,613 | -884,725 | -3,008,065 | -15,040,325 |
