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 264,215,849, 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 | 264,215,849 | |
| -1 | -264,215,849 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 264,215,849.
Example:
1 x 264,215,849 = 264,215,849
and
-1 x -264,215,849 = 264,215,849
Notice both answers equal 264,215,849
With that explanation out of the way, let's continue. Next, we take the number 264,215,849 and divide it by 2:
264,215,849 ÷ 2 = 132,107,924.5
If the quotient is a whole number, then 2 and 132,107,924.5 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 | 264,215,849 | |
| -1 | -264,215,849 |
Now, we try dividing 264,215,849 by 3:
264,215,849 ÷ 3 = 88,071,949.6667
If the quotient is a whole number, then 3 and 88,071,949.6667 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 | 264,215,849 | |
| -1 | -264,215,849 |
Let's try dividing by 4:
264,215,849 ÷ 4 = 66,053,962.25
If the quotient is a whole number, then 4 and 66,053,962.25 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 | 264,215,849 | |
| -1 | 264,215,849 |
If you did it right, you will end up with this table:
| 1 | 41 | 107 | 229 | 263 | 4,387 | 9,389 | 10,783 | 24,503 | 28,141 | 60,227 | 1,004,623 | 1,153,781 | 2,469,307 | 6,444,289 | 264,215,849 |
| -1 | -41 | -107 | -229 | -263 | -4,387 | -9,389 | -10,783 | -24,503 | -28,141 | -60,227 | -1,004,623 | -1,153,781 | -2,469,307 | -6,444,289 | -264,215,849 |
