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 538,652,765, 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 | 538,652,765 | |
| -1 | -538,652,765 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 538,652,765.
Example:
1 x 538,652,765 = 538,652,765
and
-1 x -538,652,765 = 538,652,765
Notice both answers equal 538,652,765
With that explanation out of the way, let's continue. Next, we take the number 538,652,765 and divide it by 2:
538,652,765 ÷ 2 = 269,326,382.5
If the quotient is a whole number, then 2 and 269,326,382.5 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 | 538,652,765 | |
| -1 | -538,652,765 |
Now, we try dividing 538,652,765 by 3:
538,652,765 ÷ 3 = 179,550,921.6667
If the quotient is a whole number, then 3 and 179,550,921.6667 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 | 538,652,765 | |
| -1 | -538,652,765 |
Let's try dividing by 4:
538,652,765 ÷ 4 = 134,663,191.25
If the quotient is a whole number, then 4 and 134,663,191.25 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 | 538,652,765 | |
| -1 | 538,652,765 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 73 | 365 | 511 | 2,555 | 210,823 | 1,054,115 | 1,475,761 | 7,378,805 | 15,390,079 | 76,950,395 | 107,730,553 | 538,652,765 |
| -1 | -5 | -7 | -35 | -73 | -365 | -511 | -2,555 | -210,823 | -1,054,115 | -1,475,761 | -7,378,805 | -15,390,079 | -76,950,395 | -107,730,553 | -538,652,765 |
