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 24,653,089, 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 | 24,653,089 | |
| -1 | -24,653,089 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,653,089.
Example:
1 x 24,653,089 = 24,653,089
and
-1 x -24,653,089 = 24,653,089
Notice both answers equal 24,653,089
With that explanation out of the way, let's continue. Next, we take the number 24,653,089 and divide it by 2:
24,653,089 ÷ 2 = 12,326,544.5
If the quotient is a whole number, then 2 and 12,326,544.5 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 | 24,653,089 | |
| -1 | -24,653,089 |
Now, we try dividing 24,653,089 by 3:
24,653,089 ÷ 3 = 8,217,696.3333
If the quotient is a whole number, then 3 and 8,217,696.3333 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 | 24,653,089 | |
| -1 | -24,653,089 |
Let's try dividing by 4:
24,653,089 ÷ 4 = 6,163,272.25
If the quotient is a whole number, then 4 and 6,163,272.25 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 | 24,653,089 | |
| -1 | 24,653,089 |
If you did it right, you will end up with this table:
| 1 | 19 | 61 | 89 | 239 | 1,159 | 1,691 | 4,541 | 5,429 | 14,579 | 21,271 | 103,151 | 277,001 | 404,149 | 1,297,531 | 24,653,089 |
| -1 | -19 | -61 | -89 | -239 | -1,159 | -1,691 | -4,541 | -5,429 | -14,579 | -21,271 | -103,151 | -277,001 | -404,149 | -1,297,531 | -24,653,089 |
