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 23,537,813, 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 | 23,537,813 | |
| -1 | -23,537,813 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,537,813.
Example:
1 x 23,537,813 = 23,537,813
and
-1 x -23,537,813 = 23,537,813
Notice both answers equal 23,537,813
With that explanation out of the way, let's continue. Next, we take the number 23,537,813 and divide it by 2:
23,537,813 ÷ 2 = 11,768,906.5
If the quotient is a whole number, then 2 and 11,768,906.5 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 | 23,537,813 | |
| -1 | -23,537,813 |
Now, we try dividing 23,537,813 by 3:
23,537,813 ÷ 3 = 7,845,937.6667
If the quotient is a whole number, then 3 and 7,845,937.6667 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 | 23,537,813 | |
| -1 | -23,537,813 |
Let's try dividing by 4:
23,537,813 ÷ 4 = 5,884,453.25
If the quotient is a whole number, then 4 and 5,884,453.25 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 | 23,537,813 | |
| -1 | 23,537,813 |
If you did it right, you will end up with this table:
| 1 | 13 | 41 | 43 | 79 | 169 | 533 | 559 | 1,027 | 1,763 | 3,239 | 3,397 | 6,929 | 7,267 | 13,351 | 22,919 | 42,107 | 44,161 | 139,277 | 297,947 | 547,391 | 574,093 | 1,810,601 | 23,537,813 |
| -1 | -13 | -41 | -43 | -79 | -169 | -533 | -559 | -1,027 | -1,763 | -3,239 | -3,397 | -6,929 | -7,267 | -13,351 | -22,919 | -42,107 | -44,161 | -139,277 | -297,947 | -547,391 | -574,093 | -1,810,601 | -23,537,813 |
