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 304,521,553, 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 | 304,521,553 | |
| -1 | -304,521,553 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 304,521,553.
Example:
1 x 304,521,553 = 304,521,553
and
-1 x -304,521,553 = 304,521,553
Notice both answers equal 304,521,553
With that explanation out of the way, let's continue. Next, we take the number 304,521,553 and divide it by 2:
304,521,553 ÷ 2 = 152,260,776.5
If the quotient is a whole number, then 2 and 152,260,776.5 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 | 304,521,553 | |
| -1 | -304,521,553 |
Now, we try dividing 304,521,553 by 3:
304,521,553 ÷ 3 = 101,507,184.3333
If the quotient is a whole number, then 3 and 101,507,184.3333 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 | 304,521,553 | |
| -1 | -304,521,553 |
Let's try dividing by 4:
304,521,553 ÷ 4 = 76,130,388.25
If the quotient is a whole number, then 4 and 76,130,388.25 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 | 304,521,553 | |
| -1 | 304,521,553 |
If you did it right, you will end up with this table:
| 1 | 7 | 113 | 367 | 791 | 1,049 | 2,569 | 7,343 | 41,471 | 118,537 | 290,297 | 384,983 | 829,759 | 2,694,881 | 43,503,079 | 304,521,553 |
| -1 | -7 | -113 | -367 | -791 | -1,049 | -2,569 | -7,343 | -41,471 | -118,537 | -290,297 | -384,983 | -829,759 | -2,694,881 | -43,503,079 | -304,521,553 |
