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 552,363,665, 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 | 552,363,665 | |
| -1 | -552,363,665 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 552,363,665.
Example:
1 x 552,363,665 = 552,363,665
and
-1 x -552,363,665 = 552,363,665
Notice both answers equal 552,363,665
With that explanation out of the way, let's continue. Next, we take the number 552,363,665 and divide it by 2:
552,363,665 ÷ 2 = 276,181,832.5
If the quotient is a whole number, then 2 and 276,181,832.5 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 | 552,363,665 | |
| -1 | -552,363,665 |
Now, we try dividing 552,363,665 by 3:
552,363,665 ÷ 3 = 184,121,221.6667
If the quotient is a whole number, then 3 and 184,121,221.6667 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 | 552,363,665 | |
| -1 | -552,363,665 |
Let's try dividing by 4:
552,363,665 ÷ 4 = 138,090,916.25
If the quotient is a whole number, then 4 and 138,090,916.25 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 | 552,363,665 | |
| -1 | 552,363,665 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 2,311 | 6,829 | 11,555 | 16,177 | 34,145 | 47,803 | 80,885 | 239,015 | 15,781,819 | 78,909,095 | 110,472,733 | 552,363,665 |
| -1 | -5 | -7 | -35 | -2,311 | -6,829 | -11,555 | -16,177 | -34,145 | -47,803 | -80,885 | -239,015 | -15,781,819 | -78,909,095 | -110,472,733 | -552,363,665 |
