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 23,408,827, 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 | 23,408,827 | |
| -1 | -23,408,827 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,408,827.
Example:
1 x 23,408,827 = 23,408,827
and
-1 x -23,408,827 = 23,408,827
Notice both answers equal 23,408,827
With that explanation out of the way, let's continue. Next, we take the number 23,408,827 and divide it by 2:
23,408,827 ÷ 2 = 11,704,413.5
If the quotient is a whole number, then 2 and 11,704,413.5 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 | 23,408,827 | |
| -1 | -23,408,827 |
Now, we try dividing 23,408,827 by 3:
23,408,827 ÷ 3 = 7,802,942.3333
If the quotient is a whole number, then 3 and 7,802,942.3333 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 | 23,408,827 | |
| -1 | -23,408,827 |
Let's try dividing by 4:
23,408,827 ÷ 4 = 5,852,206.75
If the quotient is a whole number, then 4 and 5,852,206.75 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 | 23,408,827 | |
| -1 | 23,408,827 |
If you did it right, you will end up with this table:
| 1 | 13 | 37 | 41 | 481 | 533 | 1,187 | 1,517 | 15,431 | 19,721 | 43,919 | 48,667 | 570,947 | 632,671 | 1,800,679 | 23,408,827 |
| -1 | -13 | -37 | -41 | -481 | -533 | -1,187 | -1,517 | -15,431 | -19,721 | -43,919 | -48,667 | -570,947 | -632,671 | -1,800,679 | -23,408,827 |
