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 23,205,355, 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 | 23,205,355 | |
| -1 | -23,205,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,205,355.
Example:
1 x 23,205,355 = 23,205,355
and
-1 x -23,205,355 = 23,205,355
Notice both answers equal 23,205,355
With that explanation out of the way, let's continue. Next, we take the number 23,205,355 and divide it by 2:
23,205,355 ÷ 2 = 11,602,677.5
If the quotient is a whole number, then 2 and 11,602,677.5 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 | 23,205,355 | |
| -1 | -23,205,355 |
Now, we try dividing 23,205,355 by 3:
23,205,355 ÷ 3 = 7,735,118.3333
If the quotient is a whole number, then 3 and 7,735,118.3333 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 | 23,205,355 | |
| -1 | -23,205,355 |
Let's try dividing by 4:
23,205,355 ÷ 4 = 5,801,338.75
If the quotient is a whole number, then 4 and 5,801,338.75 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 | 23,205,355 | |
| -1 | 23,205,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 139 | 173 | 193 | 695 | 865 | 965 | 24,047 | 26,827 | 33,389 | 120,235 | 134,135 | 166,945 | 4,641,071 | 23,205,355 |
| -1 | -5 | -139 | -173 | -193 | -695 | -865 | -965 | -24,047 | -26,827 | -33,389 | -120,235 | -134,135 | -166,945 | -4,641,071 | -23,205,355 |
