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 302,210,315, 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 | 302,210,315 | |
| -1 | -302,210,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 302,210,315.
Example:
1 x 302,210,315 = 302,210,315
and
-1 x -302,210,315 = 302,210,315
Notice both answers equal 302,210,315
With that explanation out of the way, let's continue. Next, we take the number 302,210,315 and divide it by 2:
302,210,315 ÷ 2 = 151,105,157.5
If the quotient is a whole number, then 2 and 151,105,157.5 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 | 302,210,315 | |
| -1 | -302,210,315 |
Now, we try dividing 302,210,315 by 3:
302,210,315 ÷ 3 = 100,736,771.6667
If the quotient is a whole number, then 3 and 100,736,771.6667 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 | 302,210,315 | |
| -1 | -302,210,315 |
Let's try dividing by 4:
302,210,315 ÷ 4 = 75,552,578.75
If the quotient is a whole number, then 4 and 75,552,578.75 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 | 302,210,315 | |
| -1 | 302,210,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 571 | 2,855 | 6,281 | 9,623 | 31,405 | 48,115 | 105,853 | 529,265 | 5,494,733 | 27,473,665 | 60,442,063 | 302,210,315 |
| -1 | -5 | -11 | -55 | -571 | -2,855 | -6,281 | -9,623 | -31,405 | -48,115 | -105,853 | -529,265 | -5,494,733 | -27,473,665 | -60,442,063 | -302,210,315 |
