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 553,220,443, 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 | 553,220,443 | |
| -1 | -553,220,443 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 553,220,443.
Example:
1 x 553,220,443 = 553,220,443
and
-1 x -553,220,443 = 553,220,443
Notice both answers equal 553,220,443
With that explanation out of the way, let's continue. Next, we take the number 553,220,443 and divide it by 2:
553,220,443 ÷ 2 = 276,610,221.5
If the quotient is a whole number, then 2 and 276,610,221.5 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 | 553,220,443 | |
| -1 | -553,220,443 |
Now, we try dividing 553,220,443 by 3:
553,220,443 ÷ 3 = 184,406,814.3333
If the quotient is a whole number, then 3 and 184,406,814.3333 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 | 553,220,443 | |
| -1 | -553,220,443 |
Let's try dividing by 4:
553,220,443 ÷ 4 = 138,305,110.75
If the quotient is a whole number, then 4 and 138,305,110.75 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 | 553,220,443 | |
| -1 | 553,220,443 |
If you did it right, you will end up with this table:
| 1 | 17 | 29 | 179 | 493 | 3,043 | 5,191 | 6,269 | 88,247 | 106,573 | 181,801 | 1,122,151 | 3,090,617 | 19,076,567 | 32,542,379 | 553,220,443 |
| -1 | -17 | -29 | -179 | -493 | -3,043 | -5,191 | -6,269 | -88,247 | -106,573 | -181,801 | -1,122,151 | -3,090,617 | -19,076,567 | -32,542,379 | -553,220,443 |
