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 24,602,215, 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 | 24,602,215 | |
| -1 | -24,602,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,602,215.
Example:
1 x 24,602,215 = 24,602,215
and
-1 x -24,602,215 = 24,602,215
Notice both answers equal 24,602,215
With that explanation out of the way, let's continue. Next, we take the number 24,602,215 and divide it by 2:
24,602,215 ÷ 2 = 12,301,107.5
If the quotient is a whole number, then 2 and 12,301,107.5 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 | 24,602,215 | |
| -1 | -24,602,215 |
Now, we try dividing 24,602,215 by 3:
24,602,215 ÷ 3 = 8,200,738.3333
If the quotient is a whole number, then 3 and 8,200,738.3333 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 | 24,602,215 | |
| -1 | -24,602,215 |
Let's try dividing by 4:
24,602,215 ÷ 4 = 6,150,553.75
If the quotient is a whole number, then 4 and 6,150,553.75 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 | 24,602,215 | |
| -1 | 24,602,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 61 | 305 | 671 | 3,355 | 7,333 | 36,665 | 80,663 | 403,315 | 447,313 | 2,236,565 | 4,920,443 | 24,602,215 |
| -1 | -5 | -11 | -55 | -61 | -305 | -671 | -3,355 | -7,333 | -36,665 | -80,663 | -403,315 | -447,313 | -2,236,565 | -4,920,443 | -24,602,215 |
