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 30,263,219, 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 | 30,263,219 | |
| -1 | -30,263,219 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,263,219.
Example:
1 x 30,263,219 = 30,263,219
and
-1 x -30,263,219 = 30,263,219
Notice both answers equal 30,263,219
With that explanation out of the way, let's continue. Next, we take the number 30,263,219 and divide it by 2:
30,263,219 ÷ 2 = 15,131,609.5
If the quotient is a whole number, then 2 and 15,131,609.5 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 | 30,263,219 | |
| -1 | -30,263,219 |
Now, we try dividing 30,263,219 by 3:
30,263,219 ÷ 3 = 10,087,739.6667
If the quotient is a whole number, then 3 and 10,087,739.6667 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 | 30,263,219 | |
| -1 | -30,263,219 |
Let's try dividing by 4:
30,263,219 ÷ 4 = 7,565,804.75
If the quotient is a whole number, then 4 and 7,565,804.75 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 | 30,263,219 | |
| -1 | 30,263,219 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 139 | 973 | 1,637 | 2,641 | 11,459 | 18,487 | 31,103 | 217,721 | 227,543 | 1,592,801 | 4,323,317 | 30,263,219 |
| -1 | -7 | -19 | -133 | -139 | -973 | -1,637 | -2,641 | -11,459 | -18,487 | -31,103 | -217,721 | -227,543 | -1,592,801 | -4,323,317 | -30,263,219 |
