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 24,330,485, 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 | 24,330,485 | |
| -1 | -24,330,485 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,330,485.
Example:
1 x 24,330,485 = 24,330,485
and
-1 x -24,330,485 = 24,330,485
Notice both answers equal 24,330,485
With that explanation out of the way, let's continue. Next, we take the number 24,330,485 and divide it by 2:
24,330,485 ÷ 2 = 12,165,242.5
If the quotient is a whole number, then 2 and 12,165,242.5 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 | 24,330,485 | |
| -1 | -24,330,485 |
Now, we try dividing 24,330,485 by 3:
24,330,485 ÷ 3 = 8,110,161.6667
If the quotient is a whole number, then 3 and 8,110,161.6667 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 | 24,330,485 | |
| -1 | -24,330,485 |
Let's try dividing by 4:
24,330,485 ÷ 4 = 6,082,621.25
If the quotient is a whole number, then 4 and 6,082,621.25 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 | 24,330,485 | |
| -1 | 24,330,485 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 197 | 985 | 1,453 | 3,349 | 7,265 | 16,745 | 24,701 | 123,505 | 286,241 | 1,431,205 | 4,866,097 | 24,330,485 |
| -1 | -5 | -17 | -85 | -197 | -985 | -1,453 | -3,349 | -7,265 | -16,745 | -24,701 | -123,505 | -286,241 | -1,431,205 | -4,866,097 | -24,330,485 |
