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 23,281,681, 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 | 23,281,681 | |
| -1 | -23,281,681 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,281,681.
Example:
1 x 23,281,681 = 23,281,681
and
-1 x -23,281,681 = 23,281,681
Notice both answers equal 23,281,681
With that explanation out of the way, let's continue. Next, we take the number 23,281,681 and divide it by 2:
23,281,681 ÷ 2 = 11,640,840.5
If the quotient is a whole number, then 2 and 11,640,840.5 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 | 23,281,681 | |
| -1 | -23,281,681 |
Now, we try dividing 23,281,681 by 3:
23,281,681 ÷ 3 = 7,760,560.3333
If the quotient is a whole number, then 3 and 7,760,560.3333 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 | 23,281,681 | |
| -1 | -23,281,681 |
Let's try dividing by 4:
23,281,681 ÷ 4 = 5,820,420.25
If the quotient is a whole number, then 4 and 5,820,420.25 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 | 23,281,681 | |
| -1 | 23,281,681 |
If you did it right, you will end up with this table:
| 1 | 23 | 53 | 71 | 269 | 1,219 | 1,633 | 3,763 | 6,187 | 14,257 | 19,099 | 86,549 | 327,911 | 439,277 | 1,012,247 | 23,281,681 |
| -1 | -23 | -53 | -71 | -269 | -1,219 | -1,633 | -3,763 | -6,187 | -14,257 | -19,099 | -86,549 | -327,911 | -439,277 | -1,012,247 | -23,281,681 |
