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 264,412,135, 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 | 264,412,135 | |
| -1 | -264,412,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 264,412,135.
Example:
1 x 264,412,135 = 264,412,135
and
-1 x -264,412,135 = 264,412,135
Notice both answers equal 264,412,135
With that explanation out of the way, let's continue. Next, we take the number 264,412,135 and divide it by 2:
264,412,135 ÷ 2 = 132,206,067.5
If the quotient is a whole number, then 2 and 132,206,067.5 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 | 264,412,135 | |
| -1 | -264,412,135 |
Now, we try dividing 264,412,135 by 3:
264,412,135 ÷ 3 = 88,137,378.3333
If the quotient is a whole number, then 3 and 88,137,378.3333 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 | 264,412,135 | |
| -1 | -264,412,135 |
Let's try dividing by 4:
264,412,135 ÷ 4 = 66,103,033.75
If the quotient is a whole number, then 4 and 66,103,033.75 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 | 264,412,135 | |
| -1 | 264,412,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 17 | 65 | 85 | 221 | 1,105 | 239,287 | 1,196,435 | 3,110,731 | 4,067,879 | 15,553,655 | 20,339,395 | 52,882,427 | 264,412,135 |
| -1 | -5 | -13 | -17 | -65 | -85 | -221 | -1,105 | -239,287 | -1,196,435 | -3,110,731 | -4,067,879 | -15,553,655 | -20,339,395 | -52,882,427 | -264,412,135 |
