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 15,252,325, 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 | 15,252,325 | |
| -1 | -15,252,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,252,325.
Example:
1 x 15,252,325 = 15,252,325
and
-1 x -15,252,325 = 15,252,325
Notice both answers equal 15,252,325
With that explanation out of the way, let's continue. Next, we take the number 15,252,325 and divide it by 2:
15,252,325 ÷ 2 = 7,626,162.5
If the quotient is a whole number, then 2 and 7,626,162.5 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 | 15,252,325 | |
| -1 | -15,252,325 |
Now, we try dividing 15,252,325 by 3:
15,252,325 ÷ 3 = 5,084,108.3333
If the quotient is a whole number, then 3 and 5,084,108.3333 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 | 15,252,325 | |
| -1 | -15,252,325 |
Let's try dividing by 4:
15,252,325 ÷ 4 = 3,813,081.25
If the quotient is a whole number, then 4 and 3,813,081.25 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 | 15,252,325 | |
| -1 | 15,252,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 37 | 55 | 185 | 275 | 407 | 925 | 1,499 | 2,035 | 7,495 | 10,175 | 16,489 | 37,475 | 55,463 | 82,445 | 277,315 | 412,225 | 610,093 | 1,386,575 | 3,050,465 | 15,252,325 |
| -1 | -5 | -11 | -25 | -37 | -55 | -185 | -275 | -407 | -925 | -1,499 | -2,035 | -7,495 | -10,175 | -16,489 | -37,475 | -55,463 | -82,445 | -277,315 | -412,225 | -610,093 | -1,386,575 | -3,050,465 | -15,252,325 |
