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 552,180,455, 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 | 552,180,455 | |
| -1 | -552,180,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 552,180,455.
Example:
1 x 552,180,455 = 552,180,455
and
-1 x -552,180,455 = 552,180,455
Notice both answers equal 552,180,455
With that explanation out of the way, let's continue. Next, we take the number 552,180,455 and divide it by 2:
552,180,455 ÷ 2 = 276,090,227.5
If the quotient is a whole number, then 2 and 276,090,227.5 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 | 552,180,455 | |
| -1 | -552,180,455 |
Now, we try dividing 552,180,455 by 3:
552,180,455 ÷ 3 = 184,060,151.6667
If the quotient is a whole number, then 3 and 184,060,151.6667 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 | 552,180,455 | |
| -1 | -552,180,455 |
Let's try dividing by 4:
552,180,455 ÷ 4 = 138,045,113.75
If the quotient is a whole number, then 4 and 138,045,113.75 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 | 552,180,455 | |
| -1 | 552,180,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 107 | 281 | 535 | 1,405 | 3,673 | 18,365 | 30,067 | 150,335 | 393,011 | 1,032,113 | 1,965,055 | 5,160,565 | 110,436,091 | 552,180,455 |
| -1 | -5 | -107 | -281 | -535 | -1,405 | -3,673 | -18,365 | -30,067 | -150,335 | -393,011 | -1,032,113 | -1,965,055 | -5,160,565 | -110,436,091 | -552,180,455 |
