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 214,513,531, 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 | 214,513,531 | |
| -1 | -214,513,531 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 214,513,531.
Example:
1 x 214,513,531 = 214,513,531
and
-1 x -214,513,531 = 214,513,531
Notice both answers equal 214,513,531
With that explanation out of the way, let's continue. Next, we take the number 214,513,531 and divide it by 2:
214,513,531 ÷ 2 = 107,256,765.5
If the quotient is a whole number, then 2 and 107,256,765.5 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 | 214,513,531 | |
| -1 | -214,513,531 |
Now, we try dividing 214,513,531 by 3:
214,513,531 ÷ 3 = 71,504,510.3333
If the quotient is a whole number, then 3 and 71,504,510.3333 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 | 214,513,531 | |
| -1 | -214,513,531 |
Let's try dividing by 4:
214,513,531 ÷ 4 = 53,628,382.75
If the quotient is a whole number, then 4 and 53,628,382.75 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 | 214,513,531 | |
| -1 | 214,513,531 |
If you did it right, you will end up with this table:
| 1 | 17 | 37 | 257 | 629 | 1,327 | 4,369 | 9,509 | 22,559 | 49,099 | 161,653 | 341,039 | 834,683 | 5,797,663 | 12,618,443 | 214,513,531 |
| -1 | -17 | -37 | -257 | -629 | -1,327 | -4,369 | -9,509 | -22,559 | -49,099 | -161,653 | -341,039 | -834,683 | -5,797,663 | -12,618,443 | -214,513,531 |
