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 552,013,145, 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 | 552,013,145 | |
| -1 | -552,013,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 552,013,145.
Example:
1 x 552,013,145 = 552,013,145
and
-1 x -552,013,145 = 552,013,145
Notice both answers equal 552,013,145
With that explanation out of the way, let's continue. Next, we take the number 552,013,145 and divide it by 2:
552,013,145 ÷ 2 = 276,006,572.5
If the quotient is a whole number, then 2 and 276,006,572.5 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 | 552,013,145 | |
| -1 | -552,013,145 |
Now, we try dividing 552,013,145 by 3:
552,013,145 ÷ 3 = 184,004,381.6667
If the quotient is a whole number, then 3 and 184,004,381.6667 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 | 552,013,145 | |
| -1 | -552,013,145 |
Let's try dividing by 4:
552,013,145 ÷ 4 = 138,003,286.25
If the quotient is a whole number, then 4 and 138,003,286.25 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 | 552,013,145 | |
| -1 | 552,013,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 59 | 215 | 295 | 2,537 | 12,685 | 43,517 | 217,585 | 1,871,231 | 2,567,503 | 9,356,155 | 12,837,515 | 110,402,629 | 552,013,145 |
| -1 | -5 | -43 | -59 | -215 | -295 | -2,537 | -12,685 | -43,517 | -217,585 | -1,871,231 | -2,567,503 | -9,356,155 | -12,837,515 | -110,402,629 | -552,013,145 |
