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 200,321,345, 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 | 200,321,345 | |
| -1 | -200,321,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 200,321,345.
Example:
1 x 200,321,345 = 200,321,345
and
-1 x -200,321,345 = 200,321,345
Notice both answers equal 200,321,345
With that explanation out of the way, let's continue. Next, we take the number 200,321,345 and divide it by 2:
200,321,345 ÷ 2 = 100,160,672.5
If the quotient is a whole number, then 2 and 100,160,672.5 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 | 200,321,345 | |
| -1 | -200,321,345 |
Now, we try dividing 200,321,345 by 3:
200,321,345 ÷ 3 = 66,773,781.6667
If the quotient is a whole number, then 3 and 66,773,781.6667 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 | 200,321,345 | |
| -1 | -200,321,345 |
Let's try dividing by 4:
200,321,345 ÷ 4 = 50,080,336.25
If the quotient is a whole number, then 4 and 50,080,336.25 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 | 200,321,345 | |
| -1 | 200,321,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 1,103 | 5,189 | 5,515 | 7,721 | 25,945 | 36,323 | 38,605 | 181,615 | 5,723,467 | 28,617,335 | 40,064,269 | 200,321,345 |
| -1 | -5 | -7 | -35 | -1,103 | -5,189 | -5,515 | -7,721 | -25,945 | -36,323 | -38,605 | -181,615 | -5,723,467 | -28,617,335 | -40,064,269 | -200,321,345 |
