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 536,665,015, 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 | 536,665,015 | |
| -1 | -536,665,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 536,665,015.
Example:
1 x 536,665,015 = 536,665,015
and
-1 x -536,665,015 = 536,665,015
Notice both answers equal 536,665,015
With that explanation out of the way, let's continue. Next, we take the number 536,665,015 and divide it by 2:
536,665,015 ÷ 2 = 268,332,507.5
If the quotient is a whole number, then 2 and 268,332,507.5 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 | 536,665,015 | |
| -1 | -536,665,015 |
Now, we try dividing 536,665,015 by 3:
536,665,015 ÷ 3 = 178,888,338.3333
If the quotient is a whole number, then 3 and 178,888,338.3333 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 | 536,665,015 | |
| -1 | -536,665,015 |
Let's try dividing by 4:
536,665,015 ÷ 4 = 134,166,253.75
If the quotient is a whole number, then 4 and 134,166,253.75 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 | 536,665,015 | |
| -1 | 536,665,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 53 | 101 | 265 | 505 | 5,353 | 20,051 | 26,765 | 100,255 | 1,062,703 | 2,025,151 | 5,313,515 | 10,125,755 | 107,333,003 | 536,665,015 |
| -1 | -5 | -53 | -101 | -265 | -505 | -5,353 | -20,051 | -26,765 | -100,255 | -1,062,703 | -2,025,151 | -5,313,515 | -10,125,755 | -107,333,003 | -536,665,015 |
