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 553,508,461, 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 | 553,508,461 | |
| -1 | -553,508,461 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 553,508,461.
Example:
1 x 553,508,461 = 553,508,461
and
-1 x -553,508,461 = 553,508,461
Notice both answers equal 553,508,461
With that explanation out of the way, let's continue. Next, we take the number 553,508,461 and divide it by 2:
553,508,461 ÷ 2 = 276,754,230.5
If the quotient is a whole number, then 2 and 276,754,230.5 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 | 553,508,461 | |
| -1 | -553,508,461 |
Now, we try dividing 553,508,461 by 3:
553,508,461 ÷ 3 = 184,502,820.3333
If the quotient is a whole number, then 3 and 184,502,820.3333 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 | 553,508,461 | |
| -1 | -553,508,461 |
Let's try dividing by 4:
553,508,461 ÷ 4 = 138,377,115.25
If the quotient is a whole number, then 4 and 138,377,115.25 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 | 553,508,461 | |
| -1 | 553,508,461 |
If you did it right, you will end up with this table:
| 1 | 11 | 281 | 331 | 541 | 3,091 | 3,641 | 5,951 | 93,011 | 152,021 | 179,071 | 1,023,121 | 1,672,231 | 1,969,781 | 50,318,951 | 553,508,461 |
| -1 | -11 | -281 | -331 | -541 | -3,091 | -3,641 | -5,951 | -93,011 | -152,021 | -179,071 | -1,023,121 | -1,672,231 | -1,969,781 | -50,318,951 | -553,508,461 |
