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 23,617,055, 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 | 23,617,055 | |
| -1 | -23,617,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,617,055.
Example:
1 x 23,617,055 = 23,617,055
and
-1 x -23,617,055 = 23,617,055
Notice both answers equal 23,617,055
With that explanation out of the way, let's continue. Next, we take the number 23,617,055 and divide it by 2:
23,617,055 ÷ 2 = 11,808,527.5
If the quotient is a whole number, then 2 and 11,808,527.5 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 | 23,617,055 | |
| -1 | -23,617,055 |
Now, we try dividing 23,617,055 by 3:
23,617,055 ÷ 3 = 7,872,351.6667
If the quotient is a whole number, then 3 and 7,872,351.6667 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 | 23,617,055 | |
| -1 | -23,617,055 |
Let's try dividing by 4:
23,617,055 ÷ 4 = 5,904,263.75
If the quotient is a whole number, then 4 and 5,904,263.75 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 | 23,617,055 | |
| -1 | 23,617,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 385 | 61,343 | 306,715 | 429,401 | 674,773 | 2,147,005 | 3,373,865 | 4,723,411 | 23,617,055 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -385 | -61,343 | -306,715 | -429,401 | -674,773 | -2,147,005 | -3,373,865 | -4,723,411 | -23,617,055 |
