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 24,053,215, 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 | 24,053,215 | |
| -1 | -24,053,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,053,215.
Example:
1 x 24,053,215 = 24,053,215
and
-1 x -24,053,215 = 24,053,215
Notice both answers equal 24,053,215
With that explanation out of the way, let's continue. Next, we take the number 24,053,215 and divide it by 2:
24,053,215 ÷ 2 = 12,026,607.5
If the quotient is a whole number, then 2 and 12,026,607.5 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 | 24,053,215 | |
| -1 | -24,053,215 |
Now, we try dividing 24,053,215 by 3:
24,053,215 ÷ 3 = 8,017,738.3333
If the quotient is a whole number, then 3 and 8,017,738.3333 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 | 24,053,215 | |
| -1 | -24,053,215 |
Let's try dividing by 4:
24,053,215 ÷ 4 = 6,013,303.75
If the quotient is a whole number, then 4 and 6,013,303.75 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 | 24,053,215 | |
| -1 | 24,053,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 61 | 85 | 305 | 1,037 | 4,639 | 5,185 | 23,195 | 78,863 | 282,979 | 394,315 | 1,414,895 | 4,810,643 | 24,053,215 |
| -1 | -5 | -17 | -61 | -85 | -305 | -1,037 | -4,639 | -5,185 | -23,195 | -78,863 | -282,979 | -394,315 | -1,414,895 | -4,810,643 | -24,053,215 |
