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 23,656,435, 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 | 23,656,435 | |
| -1 | -23,656,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,656,435.
Example:
1 x 23,656,435 = 23,656,435
and
-1 x -23,656,435 = 23,656,435
Notice both answers equal 23,656,435
With that explanation out of the way, let's continue. Next, we take the number 23,656,435 and divide it by 2:
23,656,435 ÷ 2 = 11,828,217.5
If the quotient is a whole number, then 2 and 11,828,217.5 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 | 23,656,435 | |
| -1 | -23,656,435 |
Now, we try dividing 23,656,435 by 3:
23,656,435 ÷ 3 = 7,885,478.3333
If the quotient is a whole number, then 3 and 7,885,478.3333 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 | 23,656,435 | |
| -1 | -23,656,435 |
Let's try dividing by 4:
23,656,435 ÷ 4 = 5,914,108.75
If the quotient is a whole number, then 4 and 5,914,108.75 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 | 23,656,435 | |
| -1 | 23,656,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 17 | 55 | 85 | 187 | 935 | 25,301 | 126,505 | 278,311 | 430,117 | 1,391,555 | 2,150,585 | 4,731,287 | 23,656,435 |
| -1 | -5 | -11 | -17 | -55 | -85 | -187 | -935 | -25,301 | -126,505 | -278,311 | -430,117 | -1,391,555 | -2,150,585 | -4,731,287 | -23,656,435 |
