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 214,413,235, 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 | 214,413,235 | |
| -1 | -214,413,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 214,413,235.
Example:
1 x 214,413,235 = 214,413,235
and
-1 x -214,413,235 = 214,413,235
Notice both answers equal 214,413,235
With that explanation out of the way, let's continue. Next, we take the number 214,413,235 and divide it by 2:
214,413,235 ÷ 2 = 107,206,617.5
If the quotient is a whole number, then 2 and 107,206,617.5 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 | 214,413,235 | |
| -1 | -214,413,235 |
Now, we try dividing 214,413,235 by 3:
214,413,235 ÷ 3 = 71,471,078.3333
If the quotient is a whole number, then 3 and 71,471,078.3333 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 | 214,413,235 | |
| -1 | -214,413,235 |
Let's try dividing by 4:
214,413,235 ÷ 4 = 53,603,308.75
If the quotient is a whole number, then 4 and 53,603,308.75 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 | 214,413,235 | |
| -1 | 214,413,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 149 | 277 | 745 | 1,039 | 1,385 | 5,195 | 41,273 | 154,811 | 206,365 | 287,803 | 774,055 | 1,439,015 | 42,882,647 | 214,413,235 |
| -1 | -5 | -149 | -277 | -745 | -1,039 | -1,385 | -5,195 | -41,273 | -154,811 | -206,365 | -287,803 | -774,055 | -1,439,015 | -42,882,647 | -214,413,235 |
