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 206,462,645, 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 | 206,462,645 | |
| -1 | -206,462,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 206,462,645.
Example:
1 x 206,462,645 = 206,462,645
and
-1 x -206,462,645 = 206,462,645
Notice both answers equal 206,462,645
With that explanation out of the way, let's continue. Next, we take the number 206,462,645 and divide it by 2:
206,462,645 ÷ 2 = 103,231,322.5
If the quotient is a whole number, then 2 and 103,231,322.5 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 | 206,462,645 | |
| -1 | -206,462,645 |
Now, we try dividing 206,462,645 by 3:
206,462,645 ÷ 3 = 68,820,881.6667
If the quotient is a whole number, then 3 and 68,820,881.6667 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 | 206,462,645 | |
| -1 | -206,462,645 |
Let's try dividing by 4:
206,462,645 ÷ 4 = 51,615,661.25
If the quotient is a whole number, then 4 and 51,615,661.25 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 | 206,462,645 | |
| -1 | 206,462,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 89 | 95 | 445 | 1,691 | 8,455 | 24,419 | 122,095 | 463,961 | 2,173,291 | 2,319,805 | 10,866,455 | 41,292,529 | 206,462,645 |
| -1 | -5 | -19 | -89 | -95 | -445 | -1,691 | -8,455 | -24,419 | -122,095 | -463,961 | -2,173,291 | -2,319,805 | -10,866,455 | -41,292,529 | -206,462,645 |
