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 11,817,245, 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 | 11,817,245 | |
| -1 | -11,817,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,817,245.
Example:
1 x 11,817,245 = 11,817,245
and
-1 x -11,817,245 = 11,817,245
Notice both answers equal 11,817,245
With that explanation out of the way, let's continue. Next, we take the number 11,817,245 and divide it by 2:
11,817,245 ÷ 2 = 5,908,622.5
If the quotient is a whole number, then 2 and 5,908,622.5 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 | 11,817,245 | |
| -1 | -11,817,245 |
Now, we try dividing 11,817,245 by 3:
11,817,245 ÷ 3 = 3,939,081.6667
If the quotient is a whole number, then 3 and 3,939,081.6667 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 | 11,817,245 | |
| -1 | -11,817,245 |
Let's try dividing by 4:
11,817,245 ÷ 4 = 2,954,311.25
If the quotient is a whole number, then 4 and 2,954,311.25 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 | 11,817,245 | |
| -1 | 11,817,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 37 | 55 | 185 | 407 | 2,035 | 5,807 | 29,035 | 63,877 | 214,859 | 319,385 | 1,074,295 | 2,363,449 | 11,817,245 |
| -1 | -5 | -11 | -37 | -55 | -185 | -407 | -2,035 | -5,807 | -29,035 | -63,877 | -214,859 | -319,385 | -1,074,295 | -2,363,449 | -11,817,245 |
