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 264,631,307, 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 | 264,631,307 | |
| -1 | -264,631,307 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 264,631,307.
Example:
1 x 264,631,307 = 264,631,307
and
-1 x -264,631,307 = 264,631,307
Notice both answers equal 264,631,307
With that explanation out of the way, let's continue. Next, we take the number 264,631,307 and divide it by 2:
264,631,307 ÷ 2 = 132,315,653.5
If the quotient is a whole number, then 2 and 132,315,653.5 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 | 264,631,307 | |
| -1 | -264,631,307 |
Now, we try dividing 264,631,307 by 3:
264,631,307 ÷ 3 = 88,210,435.6667
If the quotient is a whole number, then 3 and 88,210,435.6667 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 | 264,631,307 | |
| -1 | -264,631,307 |
Let's try dividing by 4:
264,631,307 ÷ 4 = 66,157,826.75
If the quotient is a whole number, then 4 and 66,157,826.75 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 | 264,631,307 | |
| -1 | 264,631,307 |
If you did it right, you will end up with this table:
| 1 | 23 | 67 | 83 | 1,541 | 1,909 | 2,069 | 5,561 | 47,587 | 127,903 | 138,623 | 171,727 | 3,188,329 | 3,949,721 | 11,505,709 | 264,631,307 |
| -1 | -23 | -67 | -83 | -1,541 | -1,909 | -2,069 | -5,561 | -47,587 | -127,903 | -138,623 | -171,727 | -3,188,329 | -3,949,721 | -11,505,709 | -264,631,307 |
