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 23,255,785, 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 | 23,255,785 | |
| -1 | -23,255,785 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,255,785.
Example:
1 x 23,255,785 = 23,255,785
and
-1 x -23,255,785 = 23,255,785
Notice both answers equal 23,255,785
With that explanation out of the way, let's continue. Next, we take the number 23,255,785 and divide it by 2:
23,255,785 ÷ 2 = 11,627,892.5
If the quotient is a whole number, then 2 and 11,627,892.5 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 | 23,255,785 | |
| -1 | -23,255,785 |
Now, we try dividing 23,255,785 by 3:
23,255,785 ÷ 3 = 7,751,928.3333
If the quotient is a whole number, then 3 and 7,751,928.3333 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 | 23,255,785 | |
| -1 | -23,255,785 |
Let's try dividing by 4:
23,255,785 ÷ 4 = 5,813,946.25
If the quotient is a whole number, then 4 and 5,813,946.25 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 | 23,255,785 | |
| -1 | 23,255,785 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 181 | 905 | 1,267 | 3,671 | 6,335 | 18,355 | 25,697 | 128,485 | 664,451 | 3,322,255 | 4,651,157 | 23,255,785 |
| -1 | -5 | -7 | -35 | -181 | -905 | -1,267 | -3,671 | -6,335 | -18,355 | -25,697 | -128,485 | -664,451 | -3,322,255 | -4,651,157 | -23,255,785 |
