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 24,447,665, 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 | 24,447,665 | |
| -1 | -24,447,665 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,447,665.
Example:
1 x 24,447,665 = 24,447,665
and
-1 x -24,447,665 = 24,447,665
Notice both answers equal 24,447,665
With that explanation out of the way, let's continue. Next, we take the number 24,447,665 and divide it by 2:
24,447,665 ÷ 2 = 12,223,832.5
If the quotient is a whole number, then 2 and 12,223,832.5 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 | 24,447,665 | |
| -1 | -24,447,665 |
Now, we try dividing 24,447,665 by 3:
24,447,665 ÷ 3 = 8,149,221.6667
If the quotient is a whole number, then 3 and 8,149,221.6667 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 | 24,447,665 | |
| -1 | -24,447,665 |
Let's try dividing by 4:
24,447,665 ÷ 4 = 6,111,916.25
If the quotient is a whole number, then 4 and 6,111,916.25 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 | 24,447,665 | |
| -1 | 24,447,665 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 337 | 1,319 | 1,685 | 3,707 | 6,595 | 14,509 | 18,535 | 72,545 | 444,503 | 2,222,515 | 4,889,533 | 24,447,665 |
| -1 | -5 | -11 | -55 | -337 | -1,319 | -1,685 | -3,707 | -6,595 | -14,509 | -18,535 | -72,545 | -444,503 | -2,222,515 | -4,889,533 | -24,447,665 |
