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 264,385, 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 | 264,385 | |
| -1 | -264,385 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 264,385.
Example:
1 x 264,385 = 264,385
and
-1 x -264,385 = 264,385
Notice both answers equal 264,385
With that explanation out of the way, let's continue. Next, we take the number 264,385 and divide it by 2:
264,385 ÷ 2 = 132,192.5
If the quotient is a whole number, then 2 and 132,192.5 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 | 264,385 | |
| -1 | -264,385 |
Now, we try dividing 264,385 by 3:
264,385 ÷ 3 = 88,128.3333
If the quotient is a whole number, then 3 and 88,128.3333 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 | 264,385 | |
| -1 | -264,385 |
Let's try dividing by 4:
264,385 ÷ 4 = 66,096.25
If the quotient is a whole number, then 4 and 66,096.25 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 | 264,385 | |
| -1 | 264,385 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 19 | 23 | 55 | 95 | 115 | 121 | 209 | 253 | 437 | 605 | 1,045 | 1,265 | 2,185 | 2,299 | 2,783 | 4,807 | 11,495 | 13,915 | 24,035 | 52,877 | 264,385 |
| -1 | -5 | -11 | -19 | -23 | -55 | -95 | -115 | -121 | -209 | -253 | -437 | -605 | -1,045 | -1,265 | -2,185 | -2,299 | -2,783 | -4,807 | -11,495 | -13,915 | -24,035 | -52,877 | -264,385 |
