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 302,243,227, 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 | 302,243,227 | |
| -1 | -302,243,227 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 302,243,227.
Example:
1 x 302,243,227 = 302,243,227
and
-1 x -302,243,227 = 302,243,227
Notice both answers equal 302,243,227
With that explanation out of the way, let's continue. Next, we take the number 302,243,227 and divide it by 2:
302,243,227 ÷ 2 = 151,121,613.5
If the quotient is a whole number, then 2 and 151,121,613.5 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 | 302,243,227 | |
| -1 | -302,243,227 |
Now, we try dividing 302,243,227 by 3:
302,243,227 ÷ 3 = 100,747,742.3333
If the quotient is a whole number, then 3 and 100,747,742.3333 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 | 302,243,227 | |
| -1 | -302,243,227 |
Let's try dividing by 4:
302,243,227 ÷ 4 = 75,560,806.75
If the quotient is a whole number, then 4 and 75,560,806.75 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 | 302,243,227 | |
| -1 | 302,243,227 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 61 | 143 | 671 | 793 | 8,723 | 34,649 | 381,139 | 450,437 | 2,113,589 | 4,954,807 | 23,249,479 | 27,476,657 | 302,243,227 |
| -1 | -11 | -13 | -61 | -143 | -671 | -793 | -8,723 | -34,649 | -381,139 | -450,437 | -2,113,589 | -4,954,807 | -23,249,479 | -27,476,657 | -302,243,227 |
