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 23,265,571, 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 | 23,265,571 | |
| -1 | -23,265,571 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,265,571.
Example:
1 x 23,265,571 = 23,265,571
and
-1 x -23,265,571 = 23,265,571
Notice both answers equal 23,265,571
With that explanation out of the way, let's continue. Next, we take the number 23,265,571 and divide it by 2:
23,265,571 ÷ 2 = 11,632,785.5
If the quotient is a whole number, then 2 and 11,632,785.5 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 | 23,265,571 | |
| -1 | -23,265,571 |
Now, we try dividing 23,265,571 by 3:
23,265,571 ÷ 3 = 7,755,190.3333
If the quotient is a whole number, then 3 and 7,755,190.3333 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 | 23,265,571 | |
| -1 | -23,265,571 |
Let's try dividing by 4:
23,265,571 ÷ 4 = 5,816,392.75
If the quotient is a whole number, then 4 and 5,816,392.75 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 | 23,265,571 | |
| -1 | 23,265,571 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 193 | 1,013 | 1,351 | 3,281 | 7,091 | 17,221 | 22,967 | 120,547 | 195,509 | 1,368,563 | 3,323,653 | 23,265,571 |
| -1 | -7 | -17 | -119 | -193 | -1,013 | -1,351 | -3,281 | -7,091 | -17,221 | -22,967 | -120,547 | -195,509 | -1,368,563 | -3,323,653 | -23,265,571 |
