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 206,446,331, 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 | 206,446,331 | |
| -1 | -206,446,331 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 206,446,331.
Example:
1 x 206,446,331 = 206,446,331
and
-1 x -206,446,331 = 206,446,331
Notice both answers equal 206,446,331
With that explanation out of the way, let's continue. Next, we take the number 206,446,331 and divide it by 2:
206,446,331 ÷ 2 = 103,223,165.5
If the quotient is a whole number, then 2 and 103,223,165.5 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 | 206,446,331 | |
| -1 | -206,446,331 |
Now, we try dividing 206,446,331 by 3:
206,446,331 ÷ 3 = 68,815,443.6667
If the quotient is a whole number, then 3 and 68,815,443.6667 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 | 206,446,331 | |
| -1 | -206,446,331 |
Let's try dividing by 4:
206,446,331 ÷ 4 = 51,611,582.75
If the quotient is a whole number, then 4 and 51,611,582.75 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 | 206,446,331 | |
| -1 | 206,446,331 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 29 | 91 | 203 | 377 | 2,639 | 78,229 | 547,603 | 1,016,977 | 2,268,641 | 7,118,839 | 15,880,487 | 29,492,333 | 206,446,331 |
| -1 | -7 | -13 | -29 | -91 | -203 | -377 | -2,639 | -78,229 | -547,603 | -1,016,977 | -2,268,641 | -7,118,839 | -15,880,487 | -29,492,333 | -206,446,331 |
