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 206,516,653, 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 | 206,516,653 | |
| -1 | -206,516,653 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 206,516,653.
Example:
1 x 206,516,653 = 206,516,653
and
-1 x -206,516,653 = 206,516,653
Notice both answers equal 206,516,653
With that explanation out of the way, let's continue. Next, we take the number 206,516,653 and divide it by 2:
206,516,653 ÷ 2 = 103,258,326.5
If the quotient is a whole number, then 2 and 103,258,326.5 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 | 206,516,653 | |
| -1 | -206,516,653 |
Now, we try dividing 206,516,653 by 3:
206,516,653 ÷ 3 = 68,838,884.3333
If the quotient is a whole number, then 3 and 68,838,884.3333 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 | 206,516,653 | |
| -1 | -206,516,653 |
Let's try dividing by 4:
206,516,653 ÷ 4 = 51,629,163.25
If the quotient is a whole number, then 4 and 51,629,163.25 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 | 206,516,653 | |
| -1 | 206,516,653 |
If you did it right, you will end up with this table:
| 1 | 7 | 113 | 131 | 791 | 917 | 1,993 | 13,951 | 14,803 | 103,621 | 225,209 | 261,083 | 1,576,463 | 1,827,581 | 29,502,379 | 206,516,653 |
| -1 | -7 | -113 | -131 | -791 | -917 | -1,993 | -13,951 | -14,803 | -103,621 | -225,209 | -261,083 | -1,576,463 | -1,827,581 | -29,502,379 | -206,516,653 |
