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 266,320,307, 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 | 266,320,307 | |
| -1 | -266,320,307 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 266,320,307.
Example:
1 x 266,320,307 = 266,320,307
and
-1 x -266,320,307 = 266,320,307
Notice both answers equal 266,320,307
With that explanation out of the way, let's continue. Next, we take the number 266,320,307 and divide it by 2:
266,320,307 ÷ 2 = 133,160,153.5
If the quotient is a whole number, then 2 and 133,160,153.5 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 | 266,320,307 | |
| -1 | -266,320,307 |
Now, we try dividing 266,320,307 by 3:
266,320,307 ÷ 3 = 88,773,435.6667
If the quotient is a whole number, then 3 and 88,773,435.6667 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 | 266,320,307 | |
| -1 | -266,320,307 |
Let's try dividing by 4:
266,320,307 ÷ 4 = 66,580,076.75
If the quotient is a whole number, then 4 and 66,580,076.75 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 | 266,320,307 | |
| -1 | 266,320,307 |
If you did it right, you will end up with this table:
| 1 | 11 | 89 | 199 | 979 | 1,367 | 2,189 | 15,037 | 17,711 | 121,663 | 194,821 | 272,033 | 1,338,293 | 2,992,363 | 24,210,937 | 266,320,307 |
| -1 | -11 | -89 | -199 | -979 | -1,367 | -2,189 | -15,037 | -17,711 | -121,663 | -194,821 | -272,033 | -1,338,293 | -2,992,363 | -24,210,937 | -266,320,307 |
