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 200,424,215, 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 | 200,424,215 | |
| -1 | -200,424,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 200,424,215.
Example:
1 x 200,424,215 = 200,424,215
and
-1 x -200,424,215 = 200,424,215
Notice both answers equal 200,424,215
With that explanation out of the way, let's continue. Next, we take the number 200,424,215 and divide it by 2:
200,424,215 ÷ 2 = 100,212,107.5
If the quotient is a whole number, then 2 and 100,212,107.5 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 | 200,424,215 | |
| -1 | -200,424,215 |
Now, we try dividing 200,424,215 by 3:
200,424,215 ÷ 3 = 66,808,071.6667
If the quotient is a whole number, then 3 and 66,808,071.6667 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 | 200,424,215 | |
| -1 | -200,424,215 |
Let's try dividing by 4:
200,424,215 ÷ 4 = 50,106,053.75
If the quotient is a whole number, then 4 and 50,106,053.75 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 | 200,424,215 | |
| -1 | 200,424,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 167 | 235 | 835 | 5,107 | 7,849 | 25,535 | 39,245 | 240,029 | 852,869 | 1,200,145 | 4,264,345 | 40,084,843 | 200,424,215 |
| -1 | -5 | -47 | -167 | -235 | -835 | -5,107 | -7,849 | -25,535 | -39,245 | -240,029 | -852,869 | -1,200,145 | -4,264,345 | -40,084,843 | -200,424,215 |
