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 23,496,407, 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 | 23,496,407 | |
| -1 | -23,496,407 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,496,407.
Example:
1 x 23,496,407 = 23,496,407
and
-1 x -23,496,407 = 23,496,407
Notice both answers equal 23,496,407
With that explanation out of the way, let's continue. Next, we take the number 23,496,407 and divide it by 2:
23,496,407 ÷ 2 = 11,748,203.5
If the quotient is a whole number, then 2 and 11,748,203.5 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 | 23,496,407 | |
| -1 | -23,496,407 |
Now, we try dividing 23,496,407 by 3:
23,496,407 ÷ 3 = 7,832,135.6667
If the quotient is a whole number, then 3 and 7,832,135.6667 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 | 23,496,407 | |
| -1 | -23,496,407 |
Let's try dividing by 4:
23,496,407 ÷ 4 = 5,874,101.75
If the quotient is a whole number, then 4 and 5,874,101.75 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 | 23,496,407 | |
| -1 | 23,496,407 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 61 | 97 | 209 | 361 | 671 | 1,067 | 1,159 | 1,843 | 3,971 | 5,917 | 12,749 | 20,273 | 22,021 | 35,017 | 65,087 | 112,423 | 242,231 | 385,187 | 1,236,653 | 2,136,037 | 23,496,407 |
| -1 | -11 | -19 | -61 | -97 | -209 | -361 | -671 | -1,067 | -1,159 | -1,843 | -3,971 | -5,917 | -12,749 | -20,273 | -22,021 | -35,017 | -65,087 | -112,423 | -242,231 | -385,187 | -1,236,653 | -2,136,037 | -23,496,407 |
