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 24,307,631, 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 | 24,307,631 | |
| -1 | -24,307,631 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,307,631.
Example:
1 x 24,307,631 = 24,307,631
and
-1 x -24,307,631 = 24,307,631
Notice both answers equal 24,307,631
With that explanation out of the way, let's continue. Next, we take the number 24,307,631 and divide it by 2:
24,307,631 ÷ 2 = 12,153,815.5
If the quotient is a whole number, then 2 and 12,153,815.5 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 | 24,307,631 | |
| -1 | -24,307,631 |
Now, we try dividing 24,307,631 by 3:
24,307,631 ÷ 3 = 8,102,543.6667
If the quotient is a whole number, then 3 and 8,102,543.6667 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 | 24,307,631 | |
| -1 | -24,307,631 |
Let's try dividing by 4:
24,307,631 ÷ 4 = 6,076,907.75
If the quotient is a whole number, then 4 and 6,076,907.75 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 | 24,307,631 | |
| -1 | 24,307,631 |
If you did it right, you will end up with this table:
| 1 | 19 | 37 | 71 | 487 | 703 | 1,349 | 2,627 | 9,253 | 18,019 | 34,577 | 49,913 | 342,361 | 656,963 | 1,279,349 | 24,307,631 |
| -1 | -19 | -37 | -71 | -487 | -703 | -1,349 | -2,627 | -9,253 | -18,019 | -34,577 | -49,913 | -342,361 | -656,963 | -1,279,349 | -24,307,631 |
