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 553,650,215, 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 | 553,650,215 | |
| -1 | -553,650,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 553,650,215.
Example:
1 x 553,650,215 = 553,650,215
and
-1 x -553,650,215 = 553,650,215
Notice both answers equal 553,650,215
With that explanation out of the way, let's continue. Next, we take the number 553,650,215 and divide it by 2:
553,650,215 ÷ 2 = 276,825,107.5
If the quotient is a whole number, then 2 and 276,825,107.5 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 | 553,650,215 | |
| -1 | -553,650,215 |
Now, we try dividing 553,650,215 by 3:
553,650,215 ÷ 3 = 184,550,071.6667
If the quotient is a whole number, then 3 and 184,550,071.6667 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 | 553,650,215 | |
| -1 | -553,650,215 |
Let's try dividing by 4:
553,650,215 ÷ 4 = 138,412,553.75
If the quotient is a whole number, then 4 and 138,412,553.75 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 | 553,650,215 | |
| -1 | 553,650,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 601 | 3,005 | 9,697 | 11,419 | 48,485 | 57,095 | 184,243 | 921,215 | 5,827,897 | 29,139,485 | 110,730,043 | 553,650,215 |
| -1 | -5 | -19 | -95 | -601 | -3,005 | -9,697 | -11,419 | -48,485 | -57,095 | -184,243 | -921,215 | -5,827,897 | -29,139,485 | -110,730,043 | -553,650,215 |
