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 23,661,125, 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 | 23,661,125 | |
| -1 | -23,661,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,661,125.
Example:
1 x 23,661,125 = 23,661,125
and
-1 x -23,661,125 = 23,661,125
Notice both answers equal 23,661,125
With that explanation out of the way, let's continue. Next, we take the number 23,661,125 and divide it by 2:
23,661,125 ÷ 2 = 11,830,562.5
If the quotient is a whole number, then 2 and 11,830,562.5 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 | 23,661,125 | |
| -1 | -23,661,125 |
Now, we try dividing 23,661,125 by 3:
23,661,125 ÷ 3 = 7,887,041.6667
If the quotient is a whole number, then 3 and 7,887,041.6667 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 | 23,661,125 | |
| -1 | -23,661,125 |
Let's try dividing by 4:
23,661,125 ÷ 4 = 5,915,281.25
If the quotient is a whole number, then 4 and 5,915,281.25 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 | 23,661,125 | |
| -1 | 23,661,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 73 | 125 | 365 | 1,825 | 2,593 | 9,125 | 12,965 | 64,825 | 189,289 | 324,125 | 946,445 | 4,732,225 | 23,661,125 |
| -1 | -5 | -25 | -73 | -125 | -365 | -1,825 | -2,593 | -9,125 | -12,965 | -64,825 | -189,289 | -324,125 | -946,445 | -4,732,225 | -23,661,125 |
