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 304,668,265, 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 | 304,668,265 | |
| -1 | -304,668,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 304,668,265.
Example:
1 x 304,668,265 = 304,668,265
and
-1 x -304,668,265 = 304,668,265
Notice both answers equal 304,668,265
With that explanation out of the way, let's continue. Next, we take the number 304,668,265 and divide it by 2:
304,668,265 ÷ 2 = 152,334,132.5
If the quotient is a whole number, then 2 and 152,334,132.5 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 | 304,668,265 | |
| -1 | -304,668,265 |
Now, we try dividing 304,668,265 by 3:
304,668,265 ÷ 3 = 101,556,088.3333
If the quotient is a whole number, then 3 and 101,556,088.3333 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 | 304,668,265 | |
| -1 | -304,668,265 |
Let's try dividing by 4:
304,668,265 ÷ 4 = 76,167,066.25
If the quotient is a whole number, then 4 and 76,167,066.25 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 | 304,668,265 | |
| -1 | 304,668,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 373 | 1,865 | 4,103 | 14,851 | 20,515 | 74,255 | 163,361 | 816,805 | 5,539,423 | 27,697,115 | 60,933,653 | 304,668,265 |
| -1 | -5 | -11 | -55 | -373 | -1,865 | -4,103 | -14,851 | -20,515 | -74,255 | -163,361 | -816,805 | -5,539,423 | -27,697,115 | -60,933,653 | -304,668,265 |
