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 23,004,655, 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 | 23,004,655 | |
| -1 | -23,004,655 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,004,655.
Example:
1 x 23,004,655 = 23,004,655
and
-1 x -23,004,655 = 23,004,655
Notice both answers equal 23,004,655
With that explanation out of the way, let's continue. Next, we take the number 23,004,655 and divide it by 2:
23,004,655 ÷ 2 = 11,502,327.5
If the quotient is a whole number, then 2 and 11,502,327.5 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 | 23,004,655 | |
| -1 | -23,004,655 |
Now, we try dividing 23,004,655 by 3:
23,004,655 ÷ 3 = 7,668,218.3333
If the quotient is a whole number, then 3 and 7,668,218.3333 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 | 23,004,655 | |
| -1 | -23,004,655 |
Let's try dividing by 4:
23,004,655 ÷ 4 = 5,751,163.75
If the quotient is a whole number, then 4 and 5,751,163.75 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 | 23,004,655 | |
| -1 | 23,004,655 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 241 | 1,123 | 1,205 | 4,097 | 5,615 | 19,091 | 20,485 | 95,455 | 270,643 | 1,353,215 | 4,600,931 | 23,004,655 |
| -1 | -5 | -17 | -85 | -241 | -1,123 | -1,205 | -4,097 | -5,615 | -19,091 | -20,485 | -95,455 | -270,643 | -1,353,215 | -4,600,931 | -23,004,655 |
