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 200,384,471, 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 | 200,384,471 | |
| -1 | -200,384,471 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 200,384,471.
Example:
1 x 200,384,471 = 200,384,471
and
-1 x -200,384,471 = 200,384,471
Notice both answers equal 200,384,471
With that explanation out of the way, let's continue. Next, we take the number 200,384,471 and divide it by 2:
200,384,471 ÷ 2 = 100,192,235.5
If the quotient is a whole number, then 2 and 100,192,235.5 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 | 200,384,471 | |
| -1 | -200,384,471 |
Now, we try dividing 200,384,471 by 3:
200,384,471 ÷ 3 = 66,794,823.6667
If the quotient is a whole number, then 3 and 66,794,823.6667 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 | 200,384,471 | |
| -1 | -200,384,471 |
Let's try dividing by 4:
200,384,471 ÷ 4 = 50,096,117.75
If the quotient is a whole number, then 4 and 50,096,117.75 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 | 200,384,471 | |
| -1 | 200,384,471 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 67 | 469 | 911 | 3,283 | 4,489 | 6,377 | 31,423 | 44,639 | 61,037 | 219,961 | 427,259 | 2,990,813 | 4,089,479 | 28,626,353 | 200,384,471 |
| -1 | -7 | -49 | -67 | -469 | -911 | -3,283 | -4,489 | -6,377 | -31,423 | -44,639 | -61,037 | -219,961 | -427,259 | -2,990,813 | -4,089,479 | -28,626,353 | -200,384,471 |
