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 206,602,547, 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 | 206,602,547 | |
| -1 | -206,602,547 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 206,602,547.
Example:
1 x 206,602,547 = 206,602,547
and
-1 x -206,602,547 = 206,602,547
Notice both answers equal 206,602,547
With that explanation out of the way, let's continue. Next, we take the number 206,602,547 and divide it by 2:
206,602,547 ÷ 2 = 103,301,273.5
If the quotient is a whole number, then 2 and 103,301,273.5 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 | 206,602,547 | |
| -1 | -206,602,547 |
Now, we try dividing 206,602,547 by 3:
206,602,547 ÷ 3 = 68,867,515.6667
If the quotient is a whole number, then 3 and 68,867,515.6667 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 | 206,602,547 | |
| -1 | -206,602,547 |
Let's try dividing by 4:
206,602,547 ÷ 4 = 51,650,636.75
If the quotient is a whole number, then 4 and 51,650,636.75 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 | 206,602,547 | |
| -1 | 206,602,547 |
If you did it right, you will end up with this table:
| 1 | 17 | 61 | 167 | 1,037 | 1,193 | 2,839 | 10,187 | 20,281 | 72,773 | 173,179 | 199,231 | 1,237,141 | 3,386,927 | 12,153,091 | 206,602,547 |
| -1 | -17 | -61 | -167 | -1,037 | -1,193 | -2,839 | -10,187 | -20,281 | -72,773 | -173,179 | -199,231 | -1,237,141 | -3,386,927 | -12,153,091 | -206,602,547 |
