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 24,994,055, 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 | 24,994,055 | |
| -1 | -24,994,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,994,055.
Example:
1 x 24,994,055 = 24,994,055
and
-1 x -24,994,055 = 24,994,055
Notice both answers equal 24,994,055
With that explanation out of the way, let's continue. Next, we take the number 24,994,055 and divide it by 2:
24,994,055 ÷ 2 = 12,497,027.5
If the quotient is a whole number, then 2 and 12,497,027.5 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 | 24,994,055 | |
| -1 | -24,994,055 |
Now, we try dividing 24,994,055 by 3:
24,994,055 ÷ 3 = 8,331,351.6667
If the quotient is a whole number, then 3 and 8,331,351.6667 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 | 24,994,055 | |
| -1 | -24,994,055 |
Let's try dividing by 4:
24,994,055 ÷ 4 = 6,248,513.75
If the quotient is a whole number, then 4 and 6,248,513.75 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 | 24,994,055 | |
| -1 | 24,994,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 167 | 185 | 809 | 835 | 4,045 | 6,179 | 29,933 | 30,895 | 135,103 | 149,665 | 675,515 | 4,998,811 | 24,994,055 |
| -1 | -5 | -37 | -167 | -185 | -809 | -835 | -4,045 | -6,179 | -29,933 | -30,895 | -135,103 | -149,665 | -675,515 | -4,998,811 | -24,994,055 |
