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 24,661,145, 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 | 24,661,145 | |
| -1 | -24,661,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,661,145.
Example:
1 x 24,661,145 = 24,661,145
and
-1 x -24,661,145 = 24,661,145
Notice both answers equal 24,661,145
With that explanation out of the way, let's continue. Next, we take the number 24,661,145 and divide it by 2:
24,661,145 ÷ 2 = 12,330,572.5
If the quotient is a whole number, then 2 and 12,330,572.5 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 | 24,661,145 | |
| -1 | -24,661,145 |
Now, we try dividing 24,661,145 by 3:
24,661,145 ÷ 3 = 8,220,381.6667
If the quotient is a whole number, then 3 and 8,220,381.6667 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 | 24,661,145 | |
| -1 | -24,661,145 |
Let's try dividing by 4:
24,661,145 ÷ 4 = 6,165,286.25
If the quotient is a whole number, then 4 and 6,165,286.25 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 | 24,661,145 | |
| -1 | 24,661,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 43 | 95 | 215 | 817 | 4,085 | 6,037 | 30,185 | 114,703 | 259,591 | 573,515 | 1,297,955 | 4,932,229 | 24,661,145 |
| -1 | -5 | -19 | -43 | -95 | -215 | -817 | -4,085 | -6,037 | -30,185 | -114,703 | -259,591 | -573,515 | -1,297,955 | -4,932,229 | -24,661,145 |
