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 23,848,685, 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 | 23,848,685 | |
| -1 | -23,848,685 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,848,685.
Example:
1 x 23,848,685 = 23,848,685
and
-1 x -23,848,685 = 23,848,685
Notice both answers equal 23,848,685
With that explanation out of the way, let's continue. Next, we take the number 23,848,685 and divide it by 2:
23,848,685 ÷ 2 = 11,924,342.5
If the quotient is a whole number, then 2 and 11,924,342.5 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 | 23,848,685 | |
| -1 | -23,848,685 |
Now, we try dividing 23,848,685 by 3:
23,848,685 ÷ 3 = 7,949,561.6667
If the quotient is a whole number, then 3 and 7,949,561.6667 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 | 23,848,685 | |
| -1 | -23,848,685 |
Let's try dividing by 4:
23,848,685 ÷ 4 = 5,962,171.25
If the quotient is a whole number, then 4 and 5,962,171.25 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 | 23,848,685 | |
| -1 | 23,848,685 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 59 | 295 | 413 | 2,065 | 11,549 | 57,745 | 80,843 | 404,215 | 681,391 | 3,406,955 | 4,769,737 | 23,848,685 |
| -1 | -5 | -7 | -35 | -59 | -295 | -413 | -2,065 | -11,549 | -57,745 | -80,843 | -404,215 | -681,391 | -3,406,955 | -4,769,737 | -23,848,685 |
