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 206,132,641, 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 | 206,132,641 | |
| -1 | -206,132,641 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 206,132,641.
Example:
1 x 206,132,641 = 206,132,641
and
-1 x -206,132,641 = 206,132,641
Notice both answers equal 206,132,641
With that explanation out of the way, let's continue. Next, we take the number 206,132,641 and divide it by 2:
206,132,641 ÷ 2 = 103,066,320.5
If the quotient is a whole number, then 2 and 103,066,320.5 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 | 206,132,641 | |
| -1 | -206,132,641 |
Now, we try dividing 206,132,641 by 3:
206,132,641 ÷ 3 = 68,710,880.3333
If the quotient is a whole number, then 3 and 68,710,880.3333 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 | 206,132,641 | |
| -1 | -206,132,641 |
Let's try dividing by 4:
206,132,641 ÷ 4 = 51,533,160.25
If the quotient is a whole number, then 4 and 51,533,160.25 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 | 206,132,641 | |
| -1 | 206,132,641 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 143 | 179 | 1,969 | 2,327 | 8,053 | 25,597 | 88,583 | 104,689 | 1,151,579 | 1,441,487 | 15,856,357 | 18,739,331 | 206,132,641 |
| -1 | -11 | -13 | -143 | -179 | -1,969 | -2,327 | -8,053 | -25,597 | -88,583 | -104,689 | -1,151,579 | -1,441,487 | -15,856,357 | -18,739,331 | -206,132,641 |
