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 553,213,609, 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 | 553,213,609 | |
| -1 | -553,213,609 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 553,213,609.
Example:
1 x 553,213,609 = 553,213,609
and
-1 x -553,213,609 = 553,213,609
Notice both answers equal 553,213,609
With that explanation out of the way, let's continue. Next, we take the number 553,213,609 and divide it by 2:
553,213,609 ÷ 2 = 276,606,804.5
If the quotient is a whole number, then 2 and 276,606,804.5 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 | 553,213,609 | |
| -1 | -553,213,609 |
Now, we try dividing 553,213,609 by 3:
553,213,609 ÷ 3 = 184,404,536.3333
If the quotient is a whole number, then 3 and 184,404,536.3333 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 | 553,213,609 | |
| -1 | -553,213,609 |
Let's try dividing by 4:
553,213,609 ÷ 4 = 138,303,402.25
If the quotient is a whole number, then 4 and 138,303,402.25 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 | 553,213,609 | |
| -1 | 553,213,609 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 221 | 821 | 3,049 | 10,673 | 13,957 | 39,637 | 51,833 | 181,441 | 673,829 | 2,503,229 | 32,541,977 | 42,554,893 | 553,213,609 |
| -1 | -13 | -17 | -221 | -821 | -3,049 | -10,673 | -13,957 | -39,637 | -51,833 | -181,441 | -673,829 | -2,503,229 | -32,541,977 | -42,554,893 | -553,213,609 |
