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 552,242,161, 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 | 552,242,161 | |
| -1 | -552,242,161 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 552,242,161.
Example:
1 x 552,242,161 = 552,242,161
and
-1 x -552,242,161 = 552,242,161
Notice both answers equal 552,242,161
With that explanation out of the way, let's continue. Next, we take the number 552,242,161 and divide it by 2:
552,242,161 ÷ 2 = 276,121,080.5
If the quotient is a whole number, then 2 and 276,121,080.5 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 | 552,242,161 | |
| -1 | -552,242,161 |
Now, we try dividing 552,242,161 by 3:
552,242,161 ÷ 3 = 184,080,720.3333
If the quotient is a whole number, then 3 and 184,080,720.3333 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 | 552,242,161 | |
| -1 | -552,242,161 |
Let's try dividing by 4:
552,242,161 ÷ 4 = 138,060,540.25
If the quotient is a whole number, then 4 and 138,060,540.25 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 | 552,242,161 | |
| -1 | 552,242,161 |
If you did it right, you will end up with this table:
| 1 | 17 | 41 | 359 | 697 | 2,207 | 6,103 | 14,719 | 37,519 | 90,487 | 250,223 | 792,313 | 1,538,279 | 13,469,321 | 32,484,833 | 552,242,161 |
| -1 | -17 | -41 | -359 | -697 | -2,207 | -6,103 | -14,719 | -37,519 | -90,487 | -250,223 | -792,313 | -1,538,279 | -13,469,321 | -32,484,833 | -552,242,161 |
