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 11,793,845, 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 | 11,793,845 | |
| -1 | -11,793,845 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,793,845.
Example:
1 x 11,793,845 = 11,793,845
and
-1 x -11,793,845 = 11,793,845
Notice both answers equal 11,793,845
With that explanation out of the way, let's continue. Next, we take the number 11,793,845 and divide it by 2:
11,793,845 ÷ 2 = 5,896,922.5
If the quotient is a whole number, then 2 and 5,896,922.5 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 | 11,793,845 | |
| -1 | -11,793,845 |
Now, we try dividing 11,793,845 by 3:
11,793,845 ÷ 3 = 3,931,281.6667
If the quotient is a whole number, then 3 and 3,931,281.6667 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 | 11,793,845 | |
| -1 | -11,793,845 |
Let's try dividing by 4:
11,793,845 ÷ 4 = 2,948,461.25
If the quotient is a whole number, then 4 and 2,948,461.25 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 | 11,793,845 | |
| -1 | 11,793,845 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 211 | 1,055 | 1,477 | 1,597 | 7,385 | 7,985 | 11,179 | 55,895 | 336,967 | 1,684,835 | 2,358,769 | 11,793,845 |
| -1 | -5 | -7 | -35 | -211 | -1,055 | -1,477 | -1,597 | -7,385 | -7,985 | -11,179 | -55,895 | -336,967 | -1,684,835 | -2,358,769 | -11,793,845 |
