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 23,225,111, 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 | 23,225,111 | |
| -1 | -23,225,111 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,225,111.
Example:
1 x 23,225,111 = 23,225,111
and
-1 x -23,225,111 = 23,225,111
Notice both answers equal 23,225,111
With that explanation out of the way, let's continue. Next, we take the number 23,225,111 and divide it by 2:
23,225,111 ÷ 2 = 11,612,555.5
If the quotient is a whole number, then 2 and 11,612,555.5 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 | 23,225,111 | |
| -1 | -23,225,111 |
Now, we try dividing 23,225,111 by 3:
23,225,111 ÷ 3 = 7,741,703.6667
If the quotient is a whole number, then 3 and 7,741,703.6667 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 | 23,225,111 | |
| -1 | -23,225,111 |
Let's try dividing by 4:
23,225,111 ÷ 4 = 5,806,277.75
If the quotient is a whole number, then 4 and 5,806,277.75 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 | 23,225,111 | |
| -1 | 23,225,111 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 17 | 91 | 119 | 221 | 1,547 | 15,013 | 105,091 | 195,169 | 255,221 | 1,366,183 | 1,786,547 | 3,317,873 | 23,225,111 |
| -1 | -7 | -13 | -17 | -91 | -119 | -221 | -1,547 | -15,013 | -105,091 | -195,169 | -255,221 | -1,366,183 | -1,786,547 | -3,317,873 | -23,225,111 |
