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 11,837,285, 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 | 11,837,285 | |
| -1 | -11,837,285 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,837,285.
Example:
1 x 11,837,285 = 11,837,285
and
-1 x -11,837,285 = 11,837,285
Notice both answers equal 11,837,285
With that explanation out of the way, let's continue. Next, we take the number 11,837,285 and divide it by 2:
11,837,285 ÷ 2 = 5,918,642.5
If the quotient is a whole number, then 2 and 5,918,642.5 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 | 11,837,285 | |
| -1 | -11,837,285 |
Now, we try dividing 11,837,285 by 3:
11,837,285 ÷ 3 = 3,945,761.6667
If the quotient is a whole number, then 3 and 3,945,761.6667 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 | 11,837,285 | |
| -1 | -11,837,285 |
Let's try dividing by 4:
11,837,285 ÷ 4 = 2,959,321.25
If the quotient is a whole number, then 4 and 2,959,321.25 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 | 11,837,285 | |
| -1 | 11,837,285 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 53 | 95 | 265 | 1,007 | 2,351 | 5,035 | 11,755 | 44,669 | 124,603 | 223,345 | 623,015 | 2,367,457 | 11,837,285 |
| -1 | -5 | -19 | -53 | -95 | -265 | -1,007 | -2,351 | -5,035 | -11,755 | -44,669 | -124,603 | -223,345 | -623,015 | -2,367,457 | -11,837,285 |
