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 536,648,665, 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 | 536,648,665 | |
| -1 | -536,648,665 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 536,648,665.
Example:
1 x 536,648,665 = 536,648,665
and
-1 x -536,648,665 = 536,648,665
Notice both answers equal 536,648,665
With that explanation out of the way, let's continue. Next, we take the number 536,648,665 and divide it by 2:
536,648,665 ÷ 2 = 268,324,332.5
If the quotient is a whole number, then 2 and 268,324,332.5 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 | 536,648,665 | |
| -1 | -536,648,665 |
Now, we try dividing 536,648,665 by 3:
536,648,665 ÷ 3 = 178,882,888.3333
If the quotient is a whole number, then 3 and 178,882,888.3333 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 | 536,648,665 | |
| -1 | -536,648,665 |
Let's try dividing by 4:
536,648,665 ÷ 4 = 134,162,166.25
If the quotient is a whole number, then 4 and 134,162,166.25 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 | 536,648,665 | |
| -1 | 536,648,665 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 1,033 | 5,165 | 7,231 | 14,843 | 36,155 | 74,215 | 103,901 | 519,505 | 15,332,819 | 76,664,095 | 107,329,733 | 536,648,665 |
| -1 | -5 | -7 | -35 | -1,033 | -5,165 | -7,231 | -14,843 | -36,155 | -74,215 | -103,901 | -519,505 | -15,332,819 | -76,664,095 | -107,329,733 | -536,648,665 |
