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 23,215,325, 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 | 23,215,325 | |
| -1 | -23,215,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,215,325.
Example:
1 x 23,215,325 = 23,215,325
and
-1 x -23,215,325 = 23,215,325
Notice both answers equal 23,215,325
With that explanation out of the way, let's continue. Next, we take the number 23,215,325 and divide it by 2:
23,215,325 ÷ 2 = 11,607,662.5
If the quotient is a whole number, then 2 and 11,607,662.5 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 | 23,215,325 | |
| -1 | -23,215,325 |
Now, we try dividing 23,215,325 by 3:
23,215,325 ÷ 3 = 7,738,441.6667
If the quotient is a whole number, then 3 and 7,738,441.6667 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 | 23,215,325 | |
| -1 | -23,215,325 |
Let's try dividing by 4:
23,215,325 ÷ 4 = 5,803,831.25
If the quotient is a whole number, then 4 and 5,803,831.25 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 | 23,215,325 | |
| -1 | 23,215,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 53 | 175 | 265 | 371 | 1,325 | 1,855 | 2,503 | 9,275 | 12,515 | 17,521 | 62,575 | 87,605 | 132,659 | 438,025 | 663,295 | 928,613 | 3,316,475 | 4,643,065 | 23,215,325 |
| -1 | -5 | -7 | -25 | -35 | -53 | -175 | -265 | -371 | -1,325 | -1,855 | -2,503 | -9,275 | -12,515 | -17,521 | -62,575 | -87,605 | -132,659 | -438,025 | -663,295 | -928,613 | -3,316,475 | -4,643,065 | -23,215,325 |
