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 11,953,435, 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 | 11,953,435 | |
| -1 | -11,953,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,953,435.
Example:
1 x 11,953,435 = 11,953,435
and
-1 x -11,953,435 = 11,953,435
Notice both answers equal 11,953,435
With that explanation out of the way, let's continue. Next, we take the number 11,953,435 and divide it by 2:
11,953,435 ÷ 2 = 5,976,717.5
If the quotient is a whole number, then 2 and 5,976,717.5 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 | 11,953,435 | |
| -1 | -11,953,435 |
Now, we try dividing 11,953,435 by 3:
11,953,435 ÷ 3 = 3,984,478.3333
If the quotient is a whole number, then 3 and 3,984,478.3333 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 | 11,953,435 | |
| -1 | -11,953,435 |
Let's try dividing by 4:
11,953,435 ÷ 4 = 2,988,358.75
If the quotient is a whole number, then 4 and 2,988,358.75 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 | 11,953,435 | |
| -1 | 11,953,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 173 | 865 | 1,063 | 2,249 | 5,315 | 11,245 | 13,819 | 69,095 | 183,899 | 919,495 | 2,390,687 | 11,953,435 |
| -1 | -5 | -13 | -65 | -173 | -865 | -1,063 | -2,249 | -5,315 | -11,245 | -13,819 | -69,095 | -183,899 | -919,495 | -2,390,687 | -11,953,435 |
