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 216,530,035, 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 | 216,530,035 | |
| -1 | -216,530,035 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 216,530,035.
Example:
1 x 216,530,035 = 216,530,035
and
-1 x -216,530,035 = 216,530,035
Notice both answers equal 216,530,035
With that explanation out of the way, let's continue. Next, we take the number 216,530,035 and divide it by 2:
216,530,035 ÷ 2 = 108,265,017.5
If the quotient is a whole number, then 2 and 108,265,017.5 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 | 216,530,035 | |
| -1 | -216,530,035 |
Now, we try dividing 216,530,035 by 3:
216,530,035 ÷ 3 = 72,176,678.3333
If the quotient is a whole number, then 3 and 72,176,678.3333 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 | 216,530,035 | |
| -1 | -216,530,035 |
Let's try dividing by 4:
216,530,035 ÷ 4 = 54,132,508.75
If the quotient is a whole number, then 4 and 54,132,508.75 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 | 216,530,035 | |
| -1 | 216,530,035 |
If you did it right, you will end up with this table:
| 1 | 5 | 113 | 179 | 565 | 895 | 2,141 | 10,705 | 20,227 | 101,135 | 241,933 | 383,239 | 1,209,665 | 1,916,195 | 43,306,007 | 216,530,035 |
| -1 | -5 | -113 | -179 | -565 | -895 | -2,141 | -10,705 | -20,227 | -101,135 | -241,933 | -383,239 | -1,209,665 | -1,916,195 | -43,306,007 | -216,530,035 |
