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 200,304,299, 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 | 200,304,299 | |
| -1 | -200,304,299 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 200,304,299.
Example:
1 x 200,304,299 = 200,304,299
and
-1 x -200,304,299 = 200,304,299
Notice both answers equal 200,304,299
With that explanation out of the way, let's continue. Next, we take the number 200,304,299 and divide it by 2:
200,304,299 ÷ 2 = 100,152,149.5
If the quotient is a whole number, then 2 and 100,152,149.5 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 | 200,304,299 | |
| -1 | -200,304,299 |
Now, we try dividing 200,304,299 by 3:
200,304,299 ÷ 3 = 66,768,099.6667
If the quotient is a whole number, then 3 and 66,768,099.6667 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 | 200,304,299 | |
| -1 | -200,304,299 |
Let's try dividing by 4:
200,304,299 ÷ 4 = 50,076,074.75
If the quotient is a whole number, then 4 and 50,076,074.75 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 | 200,304,299 | |
| -1 | 200,304,299 |
If you did it right, you will end up with this table:
| 1 | 13 | 31 | 307 | 403 | 1,619 | 3,991 | 9,517 | 21,047 | 50,189 | 123,721 | 497,033 | 652,457 | 6,461,429 | 15,408,023 | 200,304,299 |
| -1 | -13 | -31 | -307 | -403 | -1,619 | -3,991 | -9,517 | -21,047 | -50,189 | -123,721 | -497,033 | -652,457 | -6,461,429 | -15,408,023 | -200,304,299 |
