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 206,433,533, 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 | 206,433,533 | |
| -1 | -206,433,533 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 206,433,533.
Example:
1 x 206,433,533 = 206,433,533
and
-1 x -206,433,533 = 206,433,533
Notice both answers equal 206,433,533
With that explanation out of the way, let's continue. Next, we take the number 206,433,533 and divide it by 2:
206,433,533 ÷ 2 = 103,216,766.5
If the quotient is a whole number, then 2 and 103,216,766.5 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 | 206,433,533 | |
| -1 | -206,433,533 |
Now, we try dividing 206,433,533 by 3:
206,433,533 ÷ 3 = 68,811,177.6667
If the quotient is a whole number, then 3 and 68,811,177.6667 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 | 206,433,533 | |
| -1 | -206,433,533 |
Let's try dividing by 4:
206,433,533 ÷ 4 = 51,608,383.25
If the quotient is a whole number, then 4 and 51,608,383.25 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 | 206,433,533 | |
| -1 | 206,433,533 |
If you did it right, you will end up with this table:
| 1 | 17 | 23 | 83 | 391 | 1,411 | 1,909 | 6,361 | 32,453 | 108,137 | 146,303 | 527,963 | 2,487,151 | 8,975,371 | 12,143,149 | 206,433,533 |
| -1 | -17 | -23 | -83 | -391 | -1,411 | -1,909 | -6,361 | -32,453 | -108,137 | -146,303 | -527,963 | -2,487,151 | -8,975,371 | -12,143,149 | -206,433,533 |
