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 264,191,317, 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 | 264,191,317 | |
| -1 | -264,191,317 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 264,191,317.
Example:
1 x 264,191,317 = 264,191,317
and
-1 x -264,191,317 = 264,191,317
Notice both answers equal 264,191,317
With that explanation out of the way, let's continue. Next, we take the number 264,191,317 and divide it by 2:
264,191,317 ÷ 2 = 132,095,658.5
If the quotient is a whole number, then 2 and 132,095,658.5 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 | 264,191,317 | |
| -1 | -264,191,317 |
Now, we try dividing 264,191,317 by 3:
264,191,317 ÷ 3 = 88,063,772.3333
If the quotient is a whole number, then 3 and 88,063,772.3333 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 | 264,191,317 | |
| -1 | -264,191,317 |
Let's try dividing by 4:
264,191,317 ÷ 4 = 66,047,829.25
If the quotient is a whole number, then 4 and 66,047,829.25 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 | 264,191,317 | |
| -1 | 264,191,317 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 239 | 299 | 3,107 | 3,697 | 5,497 | 48,061 | 71,461 | 85,031 | 883,583 | 1,105,403 | 11,486,579 | 20,322,409 | 264,191,317 |
| -1 | -13 | -23 | -239 | -299 | -3,107 | -3,697 | -5,497 | -48,061 | -71,461 | -85,031 | -883,583 | -1,105,403 | -11,486,579 | -20,322,409 | -264,191,317 |
