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 200,310,625, 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 | 200,310,625 | |
| -1 | -200,310,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 200,310,625.
Example:
1 x 200,310,625 = 200,310,625
and
-1 x -200,310,625 = 200,310,625
Notice both answers equal 200,310,625
With that explanation out of the way, let's continue. Next, we take the number 200,310,625 and divide it by 2:
200,310,625 ÷ 2 = 100,155,312.5
If the quotient is a whole number, then 2 and 100,155,312.5 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 | 200,310,625 | |
| -1 | -200,310,625 |
Now, we try dividing 200,310,625 by 3:
200,310,625 ÷ 3 = 66,770,208.3333
If the quotient is a whole number, then 3 and 66,770,208.3333 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 | 200,310,625 | |
| -1 | -200,310,625 |
Let's try dividing by 4:
200,310,625 ÷ 4 = 50,077,656.25
If the quotient is a whole number, then 4 and 50,077,656.25 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 | 200,310,625 | |
| -1 | 200,310,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 41 | 125 | 205 | 625 | 1,025 | 5,125 | 7,817 | 25,625 | 39,085 | 195,425 | 320,497 | 977,125 | 1,602,485 | 4,885,625 | 8,012,425 | 40,062,125 | 200,310,625 |
| -1 | -5 | -25 | -41 | -125 | -205 | -625 | -1,025 | -5,125 | -7,817 | -25,625 | -39,085 | -195,425 | -320,497 | -977,125 | -1,602,485 | -4,885,625 | -8,012,425 | -40,062,125 | -200,310,625 |
