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 200,010,245, 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 | 200,010,245 | |
| -1 | -200,010,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 200,010,245.
Example:
1 x 200,010,245 = 200,010,245
and
-1 x -200,010,245 = 200,010,245
Notice both answers equal 200,010,245
With that explanation out of the way, let's continue. Next, we take the number 200,010,245 and divide it by 2:
200,010,245 ÷ 2 = 100,005,122.5
If the quotient is a whole number, then 2 and 100,005,122.5 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 | 200,010,245 | |
| -1 | -200,010,245 |
Now, we try dividing 200,010,245 by 3:
200,010,245 ÷ 3 = 66,670,081.6667
If the quotient is a whole number, then 3 and 66,670,081.6667 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 | 200,010,245 | |
| -1 | -200,010,245 |
Let's try dividing by 4:
200,010,245 ÷ 4 = 50,002,561.25
If the quotient is a whole number, then 4 and 50,002,561.25 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 | 200,010,245 | |
| -1 | 200,010,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 29 | 95 | 145 | 361 | 551 | 1,805 | 2,755 | 3,821 | 10,469 | 19,105 | 52,345 | 72,599 | 110,809 | 362,995 | 554,045 | 1,379,381 | 2,105,371 | 6,896,905 | 10,526,855 | 40,002,049 | 200,010,245 |
| -1 | -5 | -19 | -29 | -95 | -145 | -361 | -551 | -1,805 | -2,755 | -3,821 | -10,469 | -19,105 | -52,345 | -72,599 | -110,809 | -362,995 | -554,045 | -1,379,381 | -2,105,371 | -6,896,905 | -10,526,855 | -40,002,049 | -200,010,245 |
