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 205,536,875, 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 | 205,536,875 | |
| -1 | -205,536,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 205,536,875.
Example:
1 x 205,536,875 = 205,536,875
and
-1 x -205,536,875 = 205,536,875
Notice both answers equal 205,536,875
With that explanation out of the way, let's continue. Next, we take the number 205,536,875 and divide it by 2:
205,536,875 ÷ 2 = 102,768,437.5
If the quotient is a whole number, then 2 and 102,768,437.5 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 | 205,536,875 | |
| -1 | -205,536,875 |
Now, we try dividing 205,536,875 by 3:
205,536,875 ÷ 3 = 68,512,291.6667
If the quotient is a whole number, then 3 and 68,512,291.6667 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 | 205,536,875 | |
| -1 | -205,536,875 |
Let's try dividing by 4:
205,536,875 ÷ 4 = 51,384,218.75
If the quotient is a whole number, then 4 and 51,384,218.75 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 | 205,536,875 | |
| -1 | 205,536,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 47 | 125 | 235 | 625 | 1,175 | 5,875 | 6,997 | 29,375 | 34,985 | 174,925 | 328,859 | 874,625 | 1,644,295 | 4,373,125 | 8,221,475 | 41,107,375 | 205,536,875 |
| -1 | -5 | -25 | -47 | -125 | -235 | -625 | -1,175 | -5,875 | -6,997 | -29,375 | -34,985 | -174,925 | -328,859 | -874,625 | -1,644,295 | -4,373,125 | -8,221,475 | -41,107,375 | -205,536,875 |
