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 302,013,211, 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 | 302,013,211 | |
| -1 | -302,013,211 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 302,013,211.
Example:
1 x 302,013,211 = 302,013,211
and
-1 x -302,013,211 = 302,013,211
Notice both answers equal 302,013,211
With that explanation out of the way, let's continue. Next, we take the number 302,013,211 and divide it by 2:
302,013,211 ÷ 2 = 151,006,605.5
If the quotient is a whole number, then 2 and 151,006,605.5 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 | 302,013,211 | |
| -1 | -302,013,211 |
Now, we try dividing 302,013,211 by 3:
302,013,211 ÷ 3 = 100,671,070.3333
If the quotient is a whole number, then 3 and 100,671,070.3333 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 | 302,013,211 | |
| -1 | -302,013,211 |
Let's try dividing by 4:
302,013,211 ÷ 4 = 75,503,302.75
If the quotient is a whole number, then 4 and 75,503,302.75 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 | 302,013,211 | |
| -1 | 302,013,211 |
If you did it right, you will end up with this table:
| 1 | 17 | 47 | 191 | 799 | 1,979 | 3,247 | 8,977 | 33,643 | 93,013 | 152,609 | 377,989 | 1,581,221 | 6,425,813 | 17,765,483 | 302,013,211 |
| -1 | -17 | -47 | -191 | -799 | -1,979 | -3,247 | -8,977 | -33,643 | -93,013 | -152,609 | -377,989 | -1,581,221 | -6,425,813 | -17,765,483 | -302,013,211 |
